Best Pedals with Reverb

Updated on 07.29.2021. For an in-depth guide to reverb, please see this article about the Best Reverb Pedals organized by Type.

A guide to the Best Reverb Pedals with Tremolo

Reverb paired with tremolo was popular with everyone from British beat groups, who often used Vox AC15 and AC30 combos, to California surf bands, who typically preferred Fender amps with onboard reverb and trem, like the Deluxe Reverb.

While the vintage amps offering this combo were obviously Mono, the advanced technology of modern stompboxes is allowing builders to come up with Stereo devices that are more and more compact. This is why we decided to organize this list in the two following categories:

• Best Reverb Pedals with Tremolo (Stereo)
• Best Reverb Pedals with Tremolo (Mono)

As usual, in our interactive galleries, a mouseover or first tap will get you a description of the pedal, while a click or second tap will open a video.

Best Reverb Pedals with Tremolo (Stereo)

The pedals in this list employ digital DSP to emulate various reverb sounds produced by springs, plates or real spaces – in Stereo, a quality that makes reverb sounds more realistic and “deep” – because that’s how we experience that effect in real life since we have two ears. However, all these pedals work just as well in Mono. When used in Stereo, these pedals will deliver a tremolo that fluctuates between the right and left channels.

Strymon Flint
Flint partners three classic and completely unique reverb algorithms with the pulsating and hypnotic tremolo pioneered in vintage amplifier tremolo circuits. The ambiance effects comprise the classic ’60s Spring Tank Reverb, the inventive ’70s Electronic Plate Reverb and the nostalgic ’80s Hall Rack Reverb, while the tremolo tones include the sonically complex ’61 Harmonic Tremolo, the swampy and sultry ’63 Power Tube Tremolo and the sharp and balanced ’65 Photocell Tremolo. Reverb has controls for Color (tone), Decay and Mix, while tremolo features knobs for Intensity and Speed. Together, they let you get everything from splashy, pulsing twang to throbbing, swampy blues and serene reverberated pads.

Keeley Hydra
A compact Stereo Reverb + Tremolo with 3 Reverb modes (Spring, Plate or Room) and tap-tempo enabled Harmonic, Vibrato, or Sine Wave Tremolo. Each effect has its own separate footswitch and can be placed first in the chain for extra flexibility. The controls have dual functions accessible by holding the Color knob, and they are clearly labeled in black fonts for Tremolo and white fonts for Reverb. Reverb Trails, remote switching system compatibility, Expression Pedal and Tap-Tempo inputs round up the features.

Source Audio True Spring Reverb
A digital pedal derived from the Ventris but built specifically to deliver the most authentic spring reverb sound. Three modes emulate classic vintage effects, while the Dwell knob simulates how hard the spring would be pushed. A button in the back turns on a Tremolo effect, also featuring three modes (Bias, Opto and Harmonic).

Fender Tre-Verb
A digital pedal that recreates all the Reverb and Tremolo Effects from the vintage Fender amps. Features two individually footswtichable effects. On the Reverb side, ’63, ’65 and a classic Plate setting, calling to mind vintage outboard ‘verb units featuring the same control set that used to be included on them. The Trem has Opto, Bias and HM (harmonic) modes, spanning the history of the effect.

Keeley Verb O Trem Workstation
A deeper version of the VoT with separate footswitches for each effect and tap-tempo functionality. Both tremolo and reverb have 8 modes (2 Spring, 3 Spring, Plate, Hall, Chamber, Room, Fugue, and Slapback for reverb and Sine Wave, Square Wave, Harmonic, Dynamic Harmonic, Pitch Vibrato, Ramp Trem, Les’Rotary Speaker, U-Vibe for the trem. A set of four more knobs controlling individual settings. The controls are pretty straightforward apart from the ones labeled “Morph,” which vary depending on the selected mode.

Comodoro Sabon
An original take on ambient stereo reverb offering Shimmer and Tremolo modes. In Shimmer mode it delivers long reverberations, while Tremolo offers a classic spring-style reverb. The Mist and Rate knob have varying functions, controlling respectively the amount and pitch of the octave in Shimmer mode and depth and rate of the LFO in Tremolo mode. The Rate knob can be controlled via Expression pedal

Best Reverb Pedals with Tremolo (Mono)

The pedals in this category offer Tremolo + Reverb combo in the classic mono configuration. They are more affordable and on average of older making, but some of them are actually analog (i.e. they have actual springs inside them!).


Keeley Verb O Trem
Designed in collaboration with Americana guitarist Eddie Heinzelman, this is a pedal for the believers of the “less-knobs-is-more” philosophy: it offers 3 flavors of tremolo (Tube Bias style, Magnatone pitch-style vibrato and Harmonic Tremolo) and four straightforward knobs including a fixed, amp-style reverb control.

Mr. Black Deluxe Plus
A simple but very well received trem-verb. Just three knobs, with fixed reverb and intensity and speed controls for the tremolo, just like in the old amps that first featured this combo. A “Deluxe” version of the Deluxe Plus adds an extra footswitch to separate reverb and tremolo.

Crazy Tube Circuit White Whale
A very tweakable real spring reverb, with knobs for depth, speed, tone and dwell and three different springs for varied depth. It also features a tremolo inspired by Fender blackface and brownface amps with its own footswitch.

Keeley Hooke
A spring reverb + Tremolo combination featuring several modes, including a Trem-Verb (emulation of the Black Face Trem-n-Verb), which delivers a deep, throbbing tremolo.; a Long Decay Trem-n-Verb and a Vibro-Spring – as an a marriage of the tremolo of  Blackface and the Magnatone’s vibrato.

Rockett Moto
$199 – A simple and musical analog/digital tremolo featuring two waveform options with a fixed spring reverb.

Ernie Ball Expression Tremolo
The Ernie Ball Expression Tremolo delivers foot-sweepable tremolo control combined with an authentic-sounding spring reverb. It has five five distinct waveforms—Slow Rise, Slow Fall, Sine, Square and classic Fender-style Harmonic—plus an onboard vintage-inspired spring reverb to create subtle or dramatic pulsating soundscapes. Control the depth, rate or both parameters simultaneously with the foot treadle and unlock a virtually limitless tonal palette.

Tone Tested Designs 1960’s
The handmade 1960’s Reverb & Tremolo combines two classic effects and features an internal trim pot that lets the pedal act as a volume boost when the tremolo effect is engaged. With controls for Reverb, Speed and Intensity, the pedal’s design recalls the simple front panels of vintage amps and makes dialing in the perfect tone a cinch. The 1960’s Reverb & Tremolo pedal is offered in classic brown-and-cream or black-and-white enclosures and runs on a 9-volt center-negative power supply.

Mojo Hand FX RVT,
This is a compact, two-mode circuit that offers a spring-style Reverb with either Tremolo or Vibrato in a simple three-knob package, just like in those vintage amps that started the trend.

Champion Leccy The Skitter
$225 – An intriguing variation on the reverb & tremolo combo, with a unique routing section that lets you apply the modulation either to the wet (reverberated) or to the clean signal only. It features 8 LFO waves for the tremolo, with the Space and Time knobs controlling, its depth and speed. The reverb is fixed in size but features a three-way toggle switch that can tame its high end for warmer, “vintagey” tones.

VHT AV-MV1 Melo-Verb
The Melo-Verb recreates the classic tremolo-and-reverb combination offered on 1960s amps with some modern additions. The two effect sections are completely independent and feature separate true-bypass switching. The all-analog tremolo section has Speed and Intensity controls, and for additional flexibility it offers modern Shape and Level controls. The Shape control adjusts the tremolo character—everything from retro floating undulations to modern square-cornered chop. When the tremolo is engaged, the Level control can be set for added boost to help the effect stand out in the mix. With the Depth control turned down, the Tremolo section can also serve as a clean boost pedal, with up to 9dB of boost from the Level control. The reverb section replicates the classic built-in tube-driven spring reverb tone and takes it one step further with the addition of Tone and Mix controls. The tones range from soft, warm and round to bright splashy “tile wall spatter.”

If your budget allows it, you may also want to look at this list of Multi-Mode Reverb Pedals – many of them also feature a Tremolo setting.


The 8 best tremolo pedals for guitar 2021: give your tone a shake-up with these killer effects

Tremolo is one of the earliest guitar effects and was commonly found built into many ’60s tube amps, such as Fender’s Vibrolux and the Vox AC30 – and now it appears in a huge variety of stompbox guises, which is why we have such rich pickings for our best tremolo pedals guide.

Essentially, the effect is a periodic variation in volume of your electric guitar signal. Link Wray’s instrumental classic Rumble is one of the most iconic examples, as is Johnny Marr’s extreme use in The Smiths’ How Soon Is Now? and Green Day’s intro to Boulevard Of Broken Dreams. As you can hear from these songs, tremolo spans a range of wobbles and chops, so let’s help you find the best tremolo pedal to suit your needs…

What is the best tremolo pedal for guitar?

Whatever tremolo sound you’re after, Source Audio’s Vertigo has you covered. Its three basic settings nail the crème de la crème of amp tremolos, including a traditional Vibrolux shimmer, the dirtier Bias wobble and the uni-vibe-esque Harmonic sound from Fender’s early-’60s ‘brownface’ amps. For wackier tones, you can tweak the shape knob or use Source Audio’s Neuro app to source alternative, more esoteric algorithms.

If you’re on a budget or just looking for a quick way to add a sense of movement to your playing, Boss’s TR-2 is a classic for a reason. Its trio of rate, depth and wave controls give you everything you need, from a gentle amp-style shimmer to a square-wave helicopter chop.

How to find the best tremolo pedal for you

When shopping for a tremolo pedal, it’s worth trying to pin down the kind of sound you’re after because there’s a huge variety of tremolo sounds out there. What virtually all tremolo pedals have in common, however, are rate and depth controls. These help you adjust the speed and intensity of the effect, while many also offer a shape knob.

Traditional tremolo pedals, such as Boss’s TR-2, would typically go between a triangle wave shape (gradual volume swells) and square wave (hard on-off) sounds, with more advanced tremolo pedals offering additional waveforms, providing more rhythmic, asymmetric settings for more experimental players.

Many tremolo pedals also aim to replicate the trems you’d find in ’60s tube amps, of which there are three main types. Optical appeared in ‘blackface’ Fender amps, and offered a kind of lopsided sine wave that became synonymous with surf and country. Bias tremolo is where actual tubes were modulated, giving a slightly dirtier, more aggressive tonality. 

Harmonic aims to capture Fender’s ‘vibrato’ effect, which actually sounds more akin to a phaser or uni-vibe. Several pedals that ape these amp-style tremolos also include a built-in spring reverb to provide the full vintage amp experience in one stompbox.

If you’re serious about making tremolo an integral part of your band’s sound, you may also want to consider a tap tempo footswitch, which enables you to accurately sync the tremolo effect to the tempo of your song, and even subdivide it into quarter-notes, triplets and a variety of other configurations.

Lastly, when it comes to choosing the best tremolo pedal for you, it’s worth bearing in mind that, because tremolo alters the volume of your guitar signal, more extreme settings can result in a perceived volume loss. That could result in your guitar getting lost in a live scenario. Many modern-day tremolos feature volume knobs, which bring your level up and compensate for any loss in signal.

These are the best tremolo pedals to buy now

The best tremolo pedal for sheer versatility


Launch price: $149/£129

Controls: Depth, speed, shape, level, mode switch

Sockets: 2x input, 2x output, power

Bypass: True bypass

Power requirements: 9V power supply

Reasons to buy

+Versatile pedal+Shape control is ace+We love Source Audio's Neuro app

Reasons to avoid

-Not much

The digital experts at Source Audio perfected the sound of three of the most iconic amp tremolo sounds with the Vertigo: the optical-style tremolo from a 1967 Fender Vibrolux; the Fender ‘brownface’ series’ Harmonic wobble; and a Bias sound, similar to the tremolo on a Vox AC30.

There’s more to it than that, of course, thanks to the shape control. This adjusts between square wave, sawtooth and everything in between, while Source Audio’s Neuro app can take the sounds into entirely different realms. The Vertigo combines authenticity and eccentricity in perfect harmony.

2. Boss TR-2

The best tremolo pedal if you need a bombproof build


Launch price: $99/£77

Controls: Rate, depth, wave

Sockets: Input, output, power

Bypass: Buffered

Power requirements: 9V power supply, 9V battery

Reasons to buy

+Rugged+Reasonably priced+Industry standard

Reasons to avoid

-No volume control

Once again, Boss is responsible for the industry standard in this arena, with the TR-2 serving active duty on countless pedalboards worldwide. Its no-nonsense operation is key to its appeal, with just rate, depth and wave controls on hand to adjust the pedal’s LFO waveform.

That’s not to say it’s not versatile: there’s a great range of speed and shape options here, from a gentle triangular undulation through to machine gun-style square-wave chops, as heard on a number of Tom Morello cuts. The lack of volume control is the pedal’s only downside, but Boss’s rock-solid build quality means it won’t be breaking down any time soon.

3. TC Electronic Pipeline

Techy types will find a lot to tinker around with here


Launch price: $128/£78

Controls: Speed, depth, volume, subdivision, mode switch

Sockets: Input, output, power

Bypass: True bypass

Power requirements: 9V power supply

Reasons to buy

+Built-in tap tremolo+On-board volume knob+Smartphone tech+Two classic sounds

This digital effort is most notable for its built-in tap tremolo for on-point tremolo times – simply hold the footswitch down for two seconds, then get stomping. A subdivision knob enables you to adjust the ratio of the wave, giving you a precision-engineered stutter.

The Pipeline also packs an onboard volume knob to counter any perceived volume loss, plus two classic sounds: a vintage, American-style amp tremolo and a more aggressive square wave cut. TC’s TonePrint technology expands the sound set even further via its computer-based editing software and smartphone preset beaming.

4. Walrus Audio Monument V2

The best tremolo pedal for those seeking amp-style wobble


Launch price: $199/£179

Controls: Volume, division, rate, shape, depth, mode switch

Sockets: Input, output, power, expression

Bypass: True bypass

Power requirements: 9V power supply

Reasons to buy

+Compact+Plenty of tricks on-board+Expression pedal controllable

Reasons to avoid


This expansive pedal boasts both harmonic and regular tremolo; the former is a chewier setting based on Fender’s ‘brownface’ amps, while the latter provides a more traditional amp-style wobble.

There are a host of other tricks onboard, including a separate tap tempo footswitch (with division knob), momentary bypass feature, and a comprehensive wave control, which delivers sine, square, ramp, lumps and a random Monument Mode. For 2019, Walrus downsized the pedal into a compact enclosure, and expanded its expression pedal-controllable options to boot.

5. Fender Tre-Verb

Load up on iconic Fender tremolo sounds


Launch price: $269/£199

Controls: Tremolo level, rate, depth, mode switch; reverb blend, tone, dwell, mode switch

Sockets: 2x input, 2x output, power

Bypass: True bypass

Power requirements: 9V power supply

Reasons to buy

+Three iconic Fender trem sounds+Tap tempo footswitch+Three reverb sounds, too

Reasons to avoid

-One of the pricier pedals here

Fender’s feature-rich Tre-Verb combines its own greatest hits of tremolo and reverb in one pedal. On the tremolo side, you get the choice of three iconic Fender sounds: Optical, Bias and Harmonic, the latter of which gives a more uni-vibe tone to proceedings.

There’s also a tap tempo footswitch for the tremolo tones, as well as a level control. Add in three reverb types – ’63 and ’65 spring types, plus a plate setting – and you’ve got a one-stop shop for vintage amp effects.

6. Ernie Ball Expression Tremolo

The best tremolo pedal for intuitive control


Launch price: $199/£199

Controls: Depth, rate, waveform, reverb

Sockets: Input, output, power

Bypass: True bypass

Power requirements: 9V power supply

Reasons to buy

+On-the-fly control+Versatile stompbox+On-board spring reverb to boot+Rugged build

If you want on-the-fly control over your tremolo tones (the secret to really nailing Link Wray’s Rumble), Ernie Ball’s Expression Tremolo is your best bet, offering adjustment over rate, depth or both via its built-in treadle.

It’s a particularly versatile offering, too, boasting five waveforms (slow rise, slow fall, sine, square and harmonic), as well as an onboard spring reverb, which can also be controlled using the treadle. The enclosure is reassuringly rugged, utilising EB’s longstanding volume pedal format, with a smooth operation and non-slip grip.

7. Supro Tremolo

How dirty do you want it?


Launch price: $219/£229

Controls: Depth, gain, speed, amplitude/harmonic mode switch

Sockets: Input, output, power

Bypass: True bypass

Power requirements: 9V power supply

Reasons to buy

+If you want it dirty+Gain knob+Gritty, vintage-style tones

Reasons to avoid

-Dirt don't come cheap

Supro’s entry in the tremolo market is an altogether dirtier offering than the other options listed here, thanks to a gain knob: turn it up and, rather than up the volume, it adjusts preamp gain to add overdriven texture to the tremolo.

Accordingly, a host of gritty, vintage-style tones are available, particularly with the choice of two ’60s-inspired tremolo sounds: traditional Bias shimmer, and the altogether phasier Harmonic mode. These sounds are adjusted with standard depth and speed knobs, while you can add an external expression pedal to tweak the speed mid-lick.

8. Electro-Harmonix Super Pulsar

The best tremolo pedal for creative types


Launch price: $237/£221

Controls: Volume, rt. Phase, wave, shape, depth, rate, envelope depth, envelope rate, wave invert switch, tap divide switch, expression mode switch, xRate switch

Sockets: 2x inputs, 2x outputs, expression, power

Bypass: True bypass

Power requirements: 9V power supply

Reasons to buy

+Great for creative guitarists+Plenty of control

Reasons to avoid

-Could be too tweakable for some

Pimping EHX’s Pulsar to the nth degree, the Super Pulsar delivers digital control of analogue stereo tremolo. Shape, depth and rate handle the usual trem duties, but take the wave control over halfway and the shape knob becomes a rhythm selector, complete with a full eight-step sequencer and some great preset patterns.

Then there’s the envelope circuit, which adjusts the depth and rate according to your playing dynamics, plus expression control over any parameter. Glitchy rhythms, rapid-fire blips, flutey fade-ins… it’s all here, and while it’s not the most straightforward of modulations, creative guitarists with time on their hands will find a lot to love.

12 of the Best Harmonic Tremolo Pedals

Chase Bliss Audio Gravitas Analog Tremolo - £299


This was my first Chase Bliss Audio pedal and I use all of its 3 modes regularly - Standard, Harmonic and Combined. It also does all those really interesting bounce/ramping features which give you more textured rhythmic output. I still feel that Chase Bliss's analog effects are genius in how they work - with the wave-shaping, onboard presets, dip-switches and tap-tempo. And I know lots of players who really love this pedal too. Even though I'm considering getting additions here and alternatives like the Subdecay TremCoder - I still feel that the Gravitas will remain as my principal tremolo pedal of choice.

Coppersound Loma Pieta Tap-Tempo Harmonic Tremolo - £199


This medium enclosure tremolo has some cool features onboard - not least the 4 different modes - Tap (Tempo), LoFi (Bass-cut), Dist (Max Grit) and DBL (Double rate). There are also 4 wave-shapes and a rather unusual Grit knob for more lo-fi textures. The final cool feature is how the rate LED changes from yellow to red when you switch from standard to harmonic mode. This particular tremolo is just a little out of the ordinary - so it may be the one for you - while for me it's a touch over-sized in its format. Nonetheless a pretty cool addition to this genre.

Drolo Twin Peaks Tap Tempo Tremolo V5 - €266 (


This has just been revised and re-launched, and of course the first batch sold out almost immediately. But as is the way with Drolo - there will be another batch along soon enough - roughly one per month. This is a really smart 4 mode harmonic tremolo - Volume Modulation (Classic) | Frequency Modulation (Harmonic) | Bass Modulation Only, fixed Treble | Treble Modulation Only, fixed bass. You also get 8 wave shapes, a Symmetry knob, 3-way Tap Tempo multiplier switch and 3-way Envelope Mode switch - Middle deactivated Enveloper detector, Up increases rate as signal increases, Down decreases rate as signal increases - you also have the Envelope knob to adjust the sensitivity of the envelope detector / trigger. All in all a quite unique take on the format - and one what I'm very interested in acquiring at some stage.

EarthQuaker Devices Night Wire V2 Harmonic Tremolo - £194


EQD usually has its own unique take on the format - and the Night Wire is no exception. The key elements here are the two toggle switches - the upper of which controls the Tremolo portion - Attack or Manual - meaning the former allows you to ramp up tempo by degree of pick attack. The second switch controls the envelope filter portion with Manual, LFO (sweeping) and Attack modes. If you roll the depth back the Night Wire will act like a fixed filter, phase-shifter or envelope-controlled-filter depending on the Frequency mode selected. Of the 4 dials the Frequency control is the unusual one - and with the combination of features here this makes for a really feature-rich experience. I would have still like tap-tempo to really though!

Fender Tre-Verb - £165


The Tre-Verb to me has always seemed to be Fender's take on the Strymon Flint - they're not identical - but superficially they are very similar - 3 Reverb modes - '63, '65 and Plate and 3 Tremolo modes - Opto, Bias and Harmonic. You also get the typical controls you would expect for each of those effect types - Blend, Dwell and Tone for the Reverb, and Level, Depth and Rate for the tremolo - it's a decent take on the format and pretty reasonably priced - but does not have some of the extra bells and whistles these others have!

Flower Pedals Dandelion Harmonic Tremolo V2 - $249 (


I liked this when it first came out - but the new V2 version is killer - with its smart Dual tremolo mode and Ramping functions. You can do all manner of secondary / alternative settings by holding down the On/Hold button - setting a secondary tremolo and fine tuning settings a la Alexander Pedals and Meris. On the surface it does not look like there's too much going on - but if you check out he above demo video you will see what really makes this pedal special. I always had the Walrus Audio Monument above this in my own compact tremolo pecking order - but these new features have elevated the Dandelion to second place here! It's been up and down my wishlist for a while - but I think I may just add this for rotation duties in the next few months.

Mr Black Pana-Trem Stereo Harmonic Tremolo - £239


This is another pretty cool take on the format - with just 3 knobs - Intensity | Shift | Frequency, 2 modes - Pulser | Panner and Presets! What you initially think is a tap-tempo footswitch is actually rather a Preset selector. This is actually a really gorgeous sounding tremolo which really uses the stereo field well - I would probably still have preferred tap-tempo here too!

Strymon Flint - £279


This was actually the very first Tremolo pedal I intended to get - before I came across the CBA Gravitas and Stone Deaf FX Tremotron and settled on those two instead. But the Flint has never left my affections - it features high amongst John Mayer's favourites too if that is any significant endorsement for you. As I've mentioned above - the Fender Tre-Verb is really very similar to this, albeit with different selections - you still get 3 Reverb and 3 Tremolo modes - for the latter - '61 harmonic | '63 tube | '65 photocell. I'm a big fan of Strymon so I would obviously pay the premium for the Strymon. I have intended to get this pedal for the longest time - and is still makes sense now - as I can have the Tremolo at the end of my chain (after stereo delay) - using a TRS splitter cable for stereo in here. This is obviously a digital effect and some purists are adamant about only having analog modulations - but I mix mine up fairly regularly - to it's not an impediment here. There are two Strymon pedals that have been on my wishlist forever - this one and the Lex Rotary - neither is really a current priority - but I feel both will be added to the Tone Library eventually - it's always good to have options and alternatives.

Subdecay Vagabond Harmonic Tremolo - £159


A relatively simple but effective all analog harmonic tremolo - you can still flick it to standard / Bias mode courtesy of the mode switch - otherwise you have just 4 controls - Speed | Intensity | Envelope Drift | Volume. There's no frills here and no tap-tempo which is obviously a big deal for me, but may not be for other players wanting a simpler and more straightforward experience.

Supro Tremolo - £229


The Supro is the simplest Harmonic Tremolo featured here - just a mode switch for - Amplitude (Standard) / Harmonic - and then 3 dials - Depth | Gain | Speed. Yet is has a huge number of fans - and you will see it on quite a number of pro pedalboards. Mick Taylor (TPS) obviously loves his and uses it as a substitute for a Uni-Vibe. I love the sound of this, but would love it more if it also came with a tap-tremolo. I'm also a tweaker at heart - which means there are several other pedals listed here which are more suitable to my preferences. For those though looking for the simplest great sounding harmonic tremolo - this is likely your best candidate.

Walrus Audio Monument V2 - £179


The V1 forerunner was always one of my favourite sounding tremolos - but a little on the large site for my needs - so it was good news all-round when Walrus shrunk down their formidable Monument to compact size - with all the feature set fully in tact - you just get the same great sounds with tap-tempo in a much more convenient enclosure size. This was for a while my second choice for Harmonic Tremolos - after the Gravitas - but the recently revamped Dandelion from Flower Pedals just pips it in its own updated version. Each does a slightly different thing - and they're both wholly worthwhile trialling to see which you like the best - you may find the hidden features of the Dandelion a little tricky to use - while everything on the Monument is straight up and straightforward - one of the best of its kind.

Zeppelin Design Quaverato Harmonic Tremolo - $189 (


This is a glorious sounding full-featured harmonic tremolo - available both in DIY kit and fully assembled editions. I have no qualms about its extended feature set or how fantastic it sounds. It is a rather large pedal though. You do get 7 knobs, 2 mode switches and several internal trim-pots and dip-switches - and of course the obligatory tap-tempo footswitch. My only issue here is one of size really - as you would be sacrificing a lot of pedalboard real estate to a single effect - however good. And there is plenty of competition from several of the more compact versions here. The Quaverato has been very well received - it's just a little larger for my preferences!

Addition! Source Audio Vertigo Tremolo - £159


My readers are getting pretty good at spotting and recommending overlooked pedals - and one such on this occasion is Source Audio's 3-Mode Vertigo Tremolo. You get Normal, Harmonic and Bias Tremolo options alongside 4 control knobs - Depth, Speed, Shape and Level. This is another great sounding tremolo - but I could have really done with a tap-tempo here too. Somewhat under the radar at the moment and therefore very reasonably priced - should be worth a gamble!

Final Thoughts

When I started the longlist I had a lot more pedals on it - some turned out to not really be proper harmonic tremolos while others were sort of inconclusive. Some of those that missed out include the Bigfoot FX Magnavibe Harmonic Tremolo, the Coldcraft Harmonic Tremolo V2 which is likely discontinued now, and the Keeley Monterey - from which you can extract a sort of Harmonic Tremolo from - but it's not necessarily official as such. As with any categories there are numerous small batch boutique pedals and many that are no longer in circulation for various reasons.


As to where my own tastes lie - I feel each pedal here has its own advantages, but all my favourites have to come with tap-tempo - and of course the more compact the better! So my own top 3 here are Gravitas, Dandelion and Monument. While I also like and will actually most probably be acquiring the Drolo Twin Peaks and the Strymon Flint - although there is not pressing priority on those.


Other players may have other requirements and preferences and prefer some fo the simple non-tap-tempo pedals here. If you are in the market for a Harmonic Tremolo than I believe I've pretty much got you covered with this selection - and you should be able to select from this list. If you feel I've overlooked something that should be here - please let me know!

The best reverb pedals 2021: 12 great options for your pedalboard

Originally used to give a bit of life to otherwise flat guitar tones, spring reverb was one of the first effects available to guitar players. These days, spring, plate, hall, shimmer and even more exotic reverb types are all available in pedal format. Sometimes, all of these modes can even be found in the same pedal, which is the subject of this best reverb pedals guide. 

Reverbs that emulated large spaces, like halls, came about once digital delays became a reality, and it wasn't long before the next logical step was taken - what about imaginary spaces? Diffusing reverbs in abstract spaces, modulating and pitch shifting reverb tails offered a new sonic frontier for space cadets. Now, there's even more options, thanks to granular synthesis and improvements in the chips used in reverb pedals.

Price: $149/£140 | Controls: FX level, time, type, tone, mode switch | Sockets: 1/4” input, 1/4” output, 1/4” infinite pedal in | Bypass: Buffered bypass | Power requirements: 150mA 9V DC

11 reverb types

Top-notch sound quality

Infinite footswitch jack

Accessing secondary functions isn't so intuitive

The lower left rotary switch knob on the Oceans 11’s front panel gives the strongest indication of the complexity lurking within this diminutive device. Here, users will find 11 different settings that consist of hall, spring, plate, reverse, echo, tremolo, modulated, dynamic, auto-infinite, shimmer and polyphonic effects. 

Several of these effects - tremolo, modulated and dynamic - have three different sets of parameters that can be selected with the mode switch. The mode switch also selects tap tempo divisions for the echo setting and engages either interval or mix edit parameters for the Poly setting. Other controls include an FX level, time (decay) and tone knobs, with the latter two also providing a secondary set of parameters that are accessible by holding down the mode button for about one second.

The sound quality of all of the effects is stellar, boasting smooth tails and pro studio-quality noise-free performance. The spring reverb setting is based on a 1962 Fender 6G15 reverb unit and delivers some of the best spring reverb effects you’ll ever hear. Echo combines delay and reverb, while tremolo applies a tremolo effect to both wet and dry hall reverb. 

Shimmer is an ethereal, octave-up reverb effect with a long, sustaining tail that produces a synth-like texture, and the polyphonic reverb applies two programmable pitch-shifts to the reverb tail to also generate complex, synth-like sounds.

Whether you want outstanding versions of bread and butter reverb effects, complex and unusual special effects or a combination of both, the Electro-Harmonix Oceans 11 Reverb is a worthy and highly affordable contender for any pedalboard, large or small.

2. Boss RV-500

Boss’s most powerful reverb processor (plus delay) to date

Price: $349/£359 | Controls: Mode, Time/Value, Pre-Delay, E. Level, Low, High, Bank Up/Down, Tap | Sockets: Stereo In/Out, Exp pedal in, USB, MIDI In/Out | Bypass: Selectable buffered or true bypass | Power requirements: 225mA 9V DC

Reverb + delay options

297 onboard patch memories

Space echo effect mode

Setting up sounds can be time consuming

Boss’s RV-500 is a large-format powerhouse, with 32-bit AD/DA, 32-bit floating point processing and 96 kHz sampling rate. The jam-packed unit boasts three footswitches, digital delay options and 12 modes with 21 unique reverb types – all with a wide range of adjustable parameters, from decay, density and modulation to EQ, ducking and more. For good measure, there’s also Roland classics like the SRV-2000 Reverb and RE-201 Space Echo.

Additionally, the RV-500 features an A/B Simul mode, making it possible to use two reverb patches at once, close to 300 onboard patch memories, selectable buffered-bypass or true-bypass operation and the capability to interface with MIDI control devices. A seemingly endless array of options and combinations, all in Boss’ most powerful and versatile reverb processor to date.

3. MXR M300 Reverb

Smart and straightforward entry from the storied effects company

Price: $199/£219 | Controls: Decay, Mix, Tone | Sockets: 1/4" TRS in (instrument), 1/4" in (expression pedal), 1/4” TRS out (stereo via splitter cable) | Bypass: True bypass | Power requirements: 240mA 9V DC

Six high-quality digital 'verbs

20 volts of headroom

Trails bypass mode

Not as versatile as some feature-heavy units

It took MXR a while to come out with a reverb pedal, but it was worth the wait and fully deserves the number 3 spot in this best reverb pedals guide. The M300 is a compact, low-noise unit constructed with the usual MXR attention to detail. The simple layout features just three knobs - Decay, Mix and Tone - with the last of those also employed to cycle through the pedal’s six verbs: Plate, Spring, Epic, Mod, Room and Pad.

There’s also a hi-fi analog dry path with 20 volts of headroom and an Exp jack that makes it possible to connect an expression pedal and blend between two different setting configurations. A trails bypass mode - a particularly cool feature - allows the reverb effect to fade out when you switch the pedal off, instead of cutting off the effect abruptly. Smart, straightforward and great-sounding, the M300 is an absolute winner.

4. Eventide Space

Explore the outer limits of 'verb with this high-quality, high-functioning pedal

Price: $499/£519 | Controls: Mix, Decay, Size, Delay, Low, High, Preset, Xnob, Ynob, FxMix, Contour, Bank up/down, Tap | Sockets: Stereo in/out, Exp pedal, Aux, In Lvl: Guitar/line, Out Lvl: Amp/line, USB, MIDI In/Out | Bypass: True analog bypass | Power requirements: 500mA 9V DC

12 studio quality verbs

100+ factory presets

Real-time expression pedal control

It's not a cheap pedal

Option paralysis could be an issue for some

Eventide’s Space boasts a wide variety of spatial effects, including basic reverbs, delays and unique combination effects, with 12 of the company’s studio-level reverb combo algorithms - Room, Plate, Spring, Hall, Reverse, Shimmer, ModEchoVerb, DualVerb, Blackhole, MangledVerb, TremoloVerb and DynaVerb - on board.

There’s also more than 100 factory presets, guitar and line-level in/out, MIDI control via USB or MIDI in, real-time control with 10 knobs, MIDI or an expression pedal, tap tempo and MIDI clock sync, mono and stereo operation and much, much more. And while Space doesn’t come cheap relative to other pedals, the unit can readily do the job of more pricey rackmount processors, making it an incredibly useful stage and studio tool.

5. Strymon NightSky

The battleship workstation

Price: $429/£439 | Controls: Mod Speed, ModDepth, Decay Length, Decay Size/Pitch, Reverb Mix, Dry Mix, Low Cut, High Cut, Interval, Shimmer, Target switch, Shape switch, Texture switch, Quantize switch, Filter switch, Shimmer switch, Glimmer switch, Drive switch, 8x Sequence/Preset switch, Inst/Line switch, On footswitch, Favorite footswitch, Infinite footswitch | Sockets: Standard inputs (L, R), standard outputs (L, R), EXP, MIDI In, MIDI Out, USB | Bypass: True | Power requirements: 9V DC power supply

Huge array of features

Loads of control over parameters

Great presets

Freeze feature

Maybe something simpler would do

Even for those used to complex pedals and software plug-ins, the NightSky is initially daunting. However, its saving grace is that more-or-less every parameter is accessible quickly via a control on the front-panel.

There's three main modes. Sparse is a tap-delay based reverb, Dense is more of a plate-style reverb, and Diffuse, as the name implies, is more of an ambient reverb. The tap delay mode can put you in the ballpark of more standard delays as well, further adding to the versatility of the NightSky.

There's dedicated controls on the front panel for adding harmonic intervals, shimmer reverb tails and modulation to the core reverb sound, plus a footswitch to trigger an infinite reverb mode.

Finally, there's also a step-sequencer in the NightSky, presumably to add experimental options akin to those in the Hologram Infinite Jets and Microcosm. It's not clear that it's a USP in the context of the NightSky, which is more of a studio reverb workstation than an esoteric weirdo box.

6. Walrus Audio Fathom

A supremely versatile ‘verb with a boutique flavor

Price: $199/£185 | Controls: Decay, dampen, mix, program, mod, X | Sockets: Input, output, power | Bypass: True bypass (switchable to buffered) | Power requirements: 100mA 9V DC

A versatile reverb with its own sound

Adjustable modulation

Sustain footswitch

Not the strongest for pitch-shifting

Walrus Audio’s entry into multi-function reverbs keeps its boutique credentials in check while offering a practical array of thoroughly usable reverb types - hall, plate, lo-fi and Sonar - each with a preset-specific parameter.

The hall and plate settings really shine here, while lo-fi’s filtered tones offer some gnarly textures for more ambient players. Sonar adds high and low octaves to the reverb trails, and although it’s not the strongest shimmer available from a compact pedal, it’s a neat extra to have in your back pocket.

The pedal’s greatest strengths are the ability to add modulation to any sound, as well as the onboard sustain footswitch, which maxes out the decay for infinite reverbs.

7. Strymon BigSky

Feature-packed pedal with phenomenal tones and options

Price: $479/£429 | Controls: Value, Decay, Pre-Delay, Mix, Tone, Param 1, Param 2, Mod, Type, Bank Up/Down, Tap | Sockets: Stereo In/Out, Exp pedal in, MIDI in/out | Bypass: True bypass | Power requirements: 300mA 9V DC

12 different reverb effects

Feature packed

Front-panel controls allow for instant parameter adjustments

An expensive pedal

One of Strymon’s “large-format” pedals, the BigSky provides 12 different reverb effects that encompass standard reverbs and special effects like swell, bloom, cloud, chorale, shimmer, magneto, nonlinear and reflections. Seven control knobs on the front panel allow users to instantly adjust parameters like decay, predelay, mix, tone, parameter 1, parameter 2 and modulation, while new settings can be saved in any of 300 preset memory locations. 

Presets are accessible in separate banks of three presets (A, B and C), which are accessible via the pedal’s three footswitches and/or the rotary value control knob. The large LED displays preset info, including its number and a programmable name. The LEDs surrounding the rotary reverb-type control change color from green to amber to let users know when a preset has been modified.

What’s more, the quality of the BigSky’s reverb sounds is simply phenomenal and actually much better than many famous digital reverb rack units from the past three decades. The reverb tails are incredibly smooth, and the special effects rank right up there with those usually found on studio gear costing well over $2,000. Playing through the Big Sky instantly provides that elusive professional sheen both onstage and in the studio.

8. Neunaber Immerse Reverberator MKII

Top-notch effects selection and sound quality

Price: $249/£269 | Controls: Effect select, mix, depth, time/tone, pre-dly/mod/blend, kill dry switch, trails switch | Sockets: 2 x 1/4” input, 2 x 1/4” output | Bypass: Buffered bypass | Power requirements: 80mA 9-12V DC

Studio-quality sounds

“Plug and play” design

Convenient kill dry and trails switches

Not much!

Unlike most studio reverb units that require advanced degrees in physics and audio engineering to program and operate, the Neunaber Immerse Reverberator MKII has a simple “plug and play” design that delivers the goods with minimal effort. A rotary switch located dead center amongst the front panel controls provides eight distinct reverb effects: W3T (wet version 3), Plate, Hall, Spring, Sustain, Echo (reverb + delay), Detune and Shimmer. The other controls consist of mix, reverb depth and two other knobs that adjust different parameters (tone/echo time/hold time and pre-delay/modulation/blend) depending on which effect is selected.

More importantly, the Immerse Reverberator MKII sounds extremely expressive and musical. The Plate, Hall and Spring reverbs are exactly that, each with the distinct character that defines those effects. The modulation of the Hall, Spring and Sustain effects is seductively rich, and the Detune effect generates lush chorused reverb with crystalline clarity. An impressive selection of effects with the sound quality of the finest pro-audio digital reverb units, in a compact format that’s both pedalboard and guitarist friendly.

9. TC Electronic Hall Of Fame 2

The much loved original HOF gets some added extras

Price: $149/£109 | Controls: Decay, level, tone, type | Sockets: Stereo input and output, USB | Bypass: True bypass (switchable to buffered) | Power requirements: 100mA 9V DC

MASH expression footswitch

Huge customization via TonePrint

Impressive shimmer capability

Needs TonePrint Editor to adjust modulation, pitch-shift, etc

The sequel to TC’s best-selling Hall Of Fame takes the successful formula - which spans the typical spring, plate, church settings, plus mod and lo-fi sounds - and adds a host of extras.

Besides a polyphonic shimmer mode, the HOF2 boasts TC’s pressure-sensitive MASH technology, which allows you to adjust the intensity of the reverb depending on how hard you push on the footswitch.

Three slots are onboard to store TonePrint presets, too - you can use TC’s computer or app-based editor to create your own sounds, as well as download artist presets.

10. Source Audio Ventris Dual Reverb

Two reverbs in one hugely versatile pedal

Price: $349/£375 | Controls: Time, Mix, Pre-Delay, Treble, Control 1, Control 2, Type, Order Switch | Sockets: 2x 1/4” input, 2x 1/4” output, control input, expression pedal in, USB | Bypass: Selectable buffered or true bypass | Power requirements: 300mA 9V DC

Two reverbs in one

Flexible routing

Authentic spring sound

Pricier than some other options

The Ventris comes from digital pedal experts Source Audio, and its killer app is the ability to run two fully independent reverbs from one modestly proportioned pedal. So, you could send one reverb left, and one right, stack one into another, or run both at once in parallel for epic trails.

It's these flexible routing options that make the Ventris such an inspiring unit to play, but the sounds are what seal the deal. Source Audio's spring emulations is one of the most accurate you'll hear, while the pedal's array of ethereal settings (E-Dome, Shimmer, Offspring) are sure to meet the needs of the most fastidious soundscapers.

The Ventris is super-easy to use right out of the box, but you can edit the whole lot and access deep parameters via Source Audio's Neuro Editor app, too.

11. Red Panda Particle V2

The exotic reverb option

Price: $299.99/£305 | Controls: Blend, Chop, Delay/Pitch, Feedback, Mode, Param, Preset | Sockets: In, Out, Expression | Bypass: True | Power requirements: 9V DC power supply

Unique sounds

Granular reverbs and freeze

Delay modes as well


Granular reverb can create pads and textures from audio inputs by chopping up and re-playing small grains or buffers of audio. Of course, this is pretty much how all delay pedals work, if you kind of squint, and so the fact that the Particle is a granular reverb pedal means it also has powerful delay modes too.

The grains are controlled by the chop and parameter controls, and in many of the modes, the particle is more of a delay pedal than a reverb. However, push the chop control into freeze territory, or experiment in the 'random' mode, and you'll discover a granular reverb in the Particle geared perfectly toward guitar use.

The version two of this already popular pedal moves the freeze control from the chop knob to a separate footswitch, making an already excellent pedal even more expressive.

12. Fender Tre-Verb

One of the best reverb pedals for vintage voicing

Price: $269/£170 | Controls: Tremolo level, rate, depth, mode switch; reverb blend, tone, dwell, mode switch | Sockets: 2x input, 2x output, power | Bypass: True bypass | Power requirements: 9V power supply

Excels at classic Fender amp reverbs

Built-in tremolo sounds

Superb build quality

Standalone reverb pedals are more versatile

For many players of an older-school persuasion, reverb peaked with Fender’s ’60s tube amps, and those iconic sounds are exactly what the guitar giant set out to capture with this vintage-voiced pedal.

Reverbs include a ’63 ‘brownface’ reverb tank, ’65 ‘blackface’ reverb tank and a studio-style plate reverb emulation, with impressive accuracy, while the optical, bias and harmonic tremolos do a great approximation of these classic effects, too.

Naturally, this isn’t the place to look for grand, soundscaping reverbs, but if you’re after vintage amp effects in one box, this is a nicely priced offering from the company behind the original sounds.


Pedal best reverb/tremolo

Tremolo Pedals

Tremolo Pedals For Sale on Reverb

In the late '40s, the first mass-produced standalone effect, the DeArmond Tremolo Control made its way into the hands of Bo Diddley, whose eponymous hit features the unit. Even before Danelectro and Gibson were adding tremolo to their amps, the effect had become intertwined with blues guitar greats, and all the music they would influence. See Muddy Waters’ “Flood” and Duane Eddy’s “Rebel Rouser” for other examples.

Few effects have been deployed so strategically and recognizably as tremolo. Perhaps that’s because the deceptively simple effect, the decreasing and increasing of volume along a waveform, is unconventional and potentially distracting, especially when compared to more naturally occurring effects like reverb, overdrive, and vibrato (pitch modulation that’s often confused with tremolo).

However, it’s hard to imagine Creedence Clearwater Revival’s “Run Through The Jungle,” The Smiths’ “How Soon Is Now,” or Radiohead’s “Bones” as such romantic examples of rock guitar without their tremolo effects.

Most tremolo effects and pedals don’t use liquid to modulate the incoming signal, as the original Tremolo Control did. Some amp-based tremolos vary the volume by controlling the amount of bias for certain tubes. Others use an optical component. These, and other types of volume manipulation have been replicated and iterated on by pedal companies for decades.

These pedals and effects range from the choppy Vox Repeat Percussion to the smooth Boss TR-2. For an explanation of the different types of waveforms that can create starkly varied tremolo effects, read our article, The 6 Types of Tremolo Explained.

What is the best reverb and tremolo pedal?

Recent trends have seen builders combining reverb and tremolo in one pedal to replicate the experience of using a vintage tube amp. The Strymon Flint, with three varieties of each effect, stands out in that category.

What is the best harmonic tremolo pedal?

Harmonic tremolo effects have seen a revival in pedal form. Many builders add a harmonic or “harm” mode to their multifunction trems, but the EarthQuaker Devices Night Wire excels by focusing on the specific sound.

What is the best mini tremolo pedal?

Many users have spoken highly of the Mooer Trelicopter. Based on the classic Demeter Treumlator, the Trelicopter packs three controls into the company's standard small pedal enclosures.

What is the best stereo tremolo pedal?

Some trem pedals offer stereo outputs for panning. Since the classic Boss PN-2 and singular SL-20 are no longer in production, we recommend Mr. Black’s Pana-Trem. Along with stereo ins and outs, it offers expression control, preset recall, and two modes.

THE BEST REVERB AND TREMOLO PEDAL EVER?! Hydra - Keeley Electronics Demo

The best guitar pedals to buy in 2021: 17 best reverb pedals

The light of your amp’s reverb is fading. You yearn for something bigger, and so you plan to depart the mortal shores of onboard spring tanks for the undying lands of reverb pedals.

Here, your reverb trails may be infinite, they may be modulated and they may even have support for nine presets, more if you use MIDI. The journey will be long, perilous and potentially quite expensive, but this guide to the best reverb pedals out there should make it easier.

Why use a reverb pedal instead of amp reverb?

When amplifiers have onboard reverb, it’s most often either a spring reverb tank or a set of digital algorithms. Both of these have limitations: switching the reverb on or off with a footswitch isn’t always possible, and control over the sound is limited to one, maybe two, knobs.

Moving over to a reverb pedal opens many more sonic options, from recreations of, and improvements on, old-school plate, hall and spring sounds, to wild, characterful and creative effects.

Where in the signal chain do you place the reverb pedal?

Reverb pedals raise an interesting question, to which there is no right answer: where do you put them in your signal chain?

Aside from your own experimentation, the biggest factor in answering this is the sound of your amplifier. Does it have heaps of headroom, or are you pushing its preamp section into natural overdrive?

If the former, then a reverb pedal should have enough room to breathe when placed between your guitar and your preamp. If the latter, you’ll get the cleanest sound from a reverb pedal when it’s in your effects loop – that is, after your preamp section and before your power amp section. If you don’t have an effects loop and you still want a clean reverb sound from a pedal, consider lowering your preamp gain, making up the difference with a dirt pedal.

That’s not to say that ‘clean’ is the only way to do things. Placing a reverb pedal before a distorting preamp section, much like placing one before a distortion, overdrive or fuzz, can have its own unique sound, one closely associated with shoegaze and post-rock.

Chase Bliss Audio and Meris Automotone CXM 1978

Chase Bliss Audio Automatone CXM 1978

+ Versatile, expansive and beautiful sounds
+ What you see is always what you get
– Expensive

The CXM 1978 is the second pedal to have Chase Bliss Audio’s Automatone form factor – that is, a wedge-shaped enclosure with motorised sliders. The crux of the pedal is a recreation of early digital reverb; it’s based on studio reverbs first heard in, you guessed it, 1978.

The result is a set of startlingly huge sounds and an even more startling amount of control. The bass and treble sliders, rather than controlling those frequencies’ presence in the mix, actually change separate decay times for each band. The location of each band can be adjusted, as can the pre-delay, overall mix and treble content – along with a number of other tweaks to the reverb algorithm’s workings.

From hi-fidelity perfection to strange, lo-fi soundscapes, the CXM 1978 really does do it all, and even though it offers massive amounts of digital save-and-recall action, thanks to those motorised sliders what you see is always what you get.

Unsurprisingly, all of this comes at quite a price – it’s certainly not a beginner’s pedal – but for some, the sounds will be more than worth it.

Price: $899/£875 Description: Studio-style plate reverb with adjustable clock rate, preset support and motorised sliders Controls: Decay time for midrange and bass, bass and midrange crossover point, pre-delay, reverb mix, independent preset recall footswitch Bypass: True bypass Mono or stereo: Stereo

Strymon NightSky

Strymon NightSky

+ Highly tweakable ambient sounds
+ Full MIDI support
– Expensive

It’s safe to say that if a pedal calls itself ‘a reverberant synthesis workstation and hands-on experimental sound design platform’, then you’re in for some massive, stereo ambience that evokes the hugeness of, well, the night sky.

This big blue box from Strymon is loaded with three core reverb textures, each of which can all be modulated with tape-esque pitch wobbles, reverberant LFO sounds or wah-like filter sweeps to the tune of five different waveforms, or an envelope that follows your playing dynamics.

A pitch-shifted shimmer voice can either add ethereal sparkle or an intimidating rumble. In fact, the shimmer section has a full selection of intervals to choose from, meaning you can shift your trails up or down by a second, fourth, fifth or octave.

Notably, there are separate controls for the wet and dry signals, and the ability to morph between two completely different sounds via an expression pedal. MIDI support also opens up 300 presets in total, or alternatively eight accessible via illuminated buttons on the pedal’s face.

Price: $429/£439 Description: Multi-function ambient delay with recallable presets and a variety of modulation modes Controls: Modulation speed, type, depth, waveform shape, low-pass and high-pass filters, pitch-shift interval, shimmer mix, reverb mix, dry mix, Bypass: True bypass Mono or stereo: Stereo

EarthQuaker Devices Afterneath V3

Earthquaker Devices

+ Unique core sound
+ Flexible expression/CV support
– Traditional reverb sounds are hard to conjure

The latest version of EQD’s Afterneath uses a tried and tested digital reverb algorithm that’s chock full of ethereal spaciness and pitch-shifting oddness – but with a few extra additions.

The pedal’s big selling point is the interaction between the Mode control and the Drag control, with the former adjusting the latter’s behaviour. The Drag control, now adjustable via an expression pedal, sweeps your reverb trail up through a certain set of pitches. The Mode control introduces varying amounts of quantisation, meaning you can have completely smooth drifting all over the place, or some arpeggiation locked to a certain scale.

It’s no ordinary reverb sound, but a healthy amount of controls means you can tame things before your pitch-shifted trails completely eclipse your playing. And if that’s precisely what you want, there’s a good chance you’ve already put the Afterneath V3 in a cart by this point.

Price: $199/£199 Description: Pitch-drifting reverb made of cascading delays with support for expression and CV control over pitch Controls: Length, diffuse, dampen, reflect, drag (pitch drift), mix Bypass: True bypass Mono or stereo: Mono

Walrus Mako R1

Walrus Mako R1

+ Massive range of sounds
+ Compact compared to some digital reverb workstation
– Not what-you-see-is-what-you-get

Walrus Audio‘s Mako series is something of a Goldilocks pedal. While this stereo reverb stompbox has all the trendy high-end bells and whistles – stereo support, huge present banks and powerful signal processing – it’s quite compact and rather fetching in its stepped enclosure. It even packs in a tap-tempo footswitch. Not bad for a pedal that measures less than 8cm across.

At its core are six reverb sounds: three traditional, three less so. The spring, hall and plate reverb all offer hi-fi recreations of the classic types. The other three ( BFR, Refract and Air) are all better suited for soundscapes.

Also handy for soundscape purposes: delay time that can extend effectively forever (or, literally forever, if you use the infinite press-and-hold footswitch), extensive modulation options, and how you can hide your note’s attack with the swell control.

Price: $349 /£319 Description: Digital multi-mode stereo reverb pedal with presets Controls: Decay, swell, dry/reverb mix, modulation rate/depth/pre-delay switch with tweak knob, EQ low/high/X switch with tune knob, preset bank A/B/C switch, six-way rotary programme switch; bypass and sustain/latch footswitches Bypass: True Bypass Mono or stereo: Stereo

Eventide Blackhole Standalone

Eventide Blackhole

+ Can be the start of a stereo signal chain
+ Wide range of ambient tones
– You might already have an H9

A standalone version of the Blackhole algorithm found on Eventide’s famed H9 and H9000 multi-effects processors, this pedal’s name should give you an indication of spatial tones it offers up.

Its voice is unapologetically modern, but that’s not to say it can’t do slightly more ‘vintage’ sounds. The Size knob, at lower settings, will happily give you some room reverb tones that almost resemble slapback delay sounds. But when increased beyond the nine-o-clock mark, things start to get big, with sprawling trails that evoke the pedal’s namesake.

A reverb sound that massive can quickly become unwieldy; lucky you have a few tools at your disposal to keep your signal tidy. Firstly, there’s Gravity, which adjusts the attack of the reverb sound, meaning it can attack with immediacy or bloom in behind your playing. To keep your dry and wet signals more separate, you’ve also got high- and low-pass filters, as well as the option to adjust these filters’ resonance for even more experimentation.

Speaking of experimentation, the Mix knob allows you to completely kill your dry signal – allowing for completely transformative, cello-like sounds and even more abstract soundscaping.

The pedal’s also firmly in the ‘workstation’ category, with five onboard presets, and 127 accessible via MIDI. An expression pedal can also blend between heel and toe presets for smooth transitions, or just some inspiring, unexpected sounds.

Price: $199/£279 Description: Standalone version of Eventide’s Blackhole reverb algorithm Controls: Mix, Gravity, Feedback, Reverb Size, low- and high-pass filter, freeze footswitch, preset recall function, secondary deep editing Bypass: True bypass Mono or stereo: Mono input, stereo output

Electro-Harmonix Oceans 12

Electro-Harmonix Oceans 12

+ Extensive controls and I/O
+ Affordable way to access huge number of sounds
– Could cause option paralysis

The EHX Oceans 12 adds a few extra controls and features to its predecessor, the Oceans 11, which is already an absurdly feature-packed little pedal. It’s billed as a “dual stereo reverb”, meaning that housed within its bigger enclosure are two reverb engines – both are completely stereo and can be run in series or parallel.

The Oceans 12 also has stereo inputs and outputs, so it should slot happily anywhere into an existing stereo rig. It can, of course, function fine in mono, too. There’s even an effects loop to add in more effects to the mix.

The biggest appeal of the Oceans 12 is the sheer number of options available. There are 12 core reverb sounds – most of which have two modes, some three – and then there are two reverb engines at work. The tones themselves range from drippy spring reverbs to shoegaze-friendly reverse reverbs to huge shimmering ambience. If you’re indecisive about the reverb tone you need at your feet, then the Oceans 12 keeps your options open.

Price: $237.60/£229 Description: Stereo reverb pedal with 12 core sounds and two independent sound engines Controls: Effect level, pre-delay, decay time and tone knobs, reverb type selector, two controls specific to each type, switchable trails, mode selector switch Bypass: Buffered bypass Mono or stereo: Stereo

EarthQuaker Devices Astral Destiny

Earthquaker Devices Astral Destiny

+ Multitude of takes on the shimmer concept
+ Stretch footswitch and expression pedal let you get weird
– Not for those who don’t like octave reverbs

This reverb is based around the shimmer sound – that is, when reverb trails are shifted an octave up or down. Per EQD fashion, however, there’s some weirder stuff at play here with several modes for a variety of reverb voices as well as in-built chorus modulation. The voices range from standard octave up or down shimmers, to stranger things such as the Astral mode, which cascades your pitch-shifted trails into themselves for blooming, chaotic ambience.

It’s versatile enough as a ‘set-and-forget’ sound to add some pitch-shifted ambience to your sound. But with the momentary Stretch footswitch, you can suddenly double the decay time of the reverb and thus warp the pitch of your repeats, an effect that’s highly interactive depending on the mode you’re in.

An expression pedal can also be mapped to either length, tone, mix or modulation depth or rate for even more interactivity.

The Astral Destiny’s focus on one style of reverb is both a pro and a con – while it might not cover the same reverb ground as a multi-reverb stompbox (no old-school spring sounds here), it dives deep into its sound niche and discovers some exciting, cosmic sounds.

Price: $199/£205 Description: Shimmer reverb with presets, modulation, and variety of pitch-shift modes and analogue dry-signal path Controls: Preset and mode selector knobs, depth, rate, tone, mix and length knobs, stretch footswitch Bypass: True bypass Mono or stereo: Mono

Keeley Caverns Delay Reverb V2

Keeley Canvas Delay Reverb V2

+ Both delay and reverb have fantastic core sounds
+ Versatile modulation options from both
– The delay is focused on analogue tape-echo rather than massive digital ambient sounds

Delay and reverb are a great combo, and so it’s no surprise that Keeley’s Caverns, which combines them both into one versatile stompbox, has become one of the brand’s most celebrated pedals.

The delay side of things offers a modulated tape echo style, although the modulation is totally optional and quite tweakable. There’s a rate knob for the speed of the modulation, and a toggle switch to choose between two different depths – or turning it off entirely. There are also controls for time, mix and repeats, with the latter being able to push the pedal into self-oscillating bliss.

The reverb side also has a toggle switch for choosing between a modulated reverb sound, spring reverb or shimmer. Handily, the modulation is appropriate to each style. The old-school spring reverb sound offers a suitable Fender black-panel-style tremolo, the modulated reverb offers adjustable chorus ambience, and the shimmer style lets you tweak how ‘fed-back’ its octave-up voice is.

The reverb side also has a dedicated warmth knob to keep the wet signal from stomping all over your playing. Both sides of the pedal can be activated independently, with their respective blend knobs keeping things balanced. If you want something slightly more out there, but don’t want to lose traditional sounds – in both the worlds of delay and reverb – the Caverns is a great choice.

Price: $179/‎£189 Description: Dual delay and reverb pedal with independent switching Controls: Reverb type, blend, warmth, modulation rate and decay time, Delay blend, time, modulation rate, repeats, and modulation amount. Bypass: Switchable true-bypass or trails Mono or stereo: Mono

Fender Tre-Verb

Fender Tre-Verb

+ Authentic Fender amp-style reverb and tremolo
+ Versatile signal path switching
– Not for ambient guitarists

When you think of the combination of tremolo and reverb, you’re likely thinking of the sound of a classic Fender amp. So who better to combine these effects into a pedal than Fender itself?

The pedal is straightforward yet versatile. The tremolo and reverb circuits are independently switchable, with tap tempo on the tremolo side to adjust its rate. The reverb side has three voices: two spring reverb emulations from 1963 and 1965 amplifiers, and one plate reverb emulation. Controls allow adjustment of the overall mix, reverb time and importantly tone, so the treble of your sound doesn’t become busy.

The tremolo side is no afterthought, either, with a switch for selection between optical, harmonic and bias modes, and depth, level and rate knobs. Handily, you can also change the order of effects – tremolo before reverb, or vice-versa.

While it won’t be for those looking to sculpt 20-minute-long cascading octave trails, there’s no better pedal for emulating the effects section of an old-school amp.

Price: $299.99/£199 Description: Dual tremolo and reverb pedal with old-school analogue-style emulations of both Controls: Tremolo rate, depth, level and type; reverb blend, tone dwell and type Bypass: True bypass Mono or stereo: Stereo

Meris Mercury7

Meris Mercury7

+ Offers two great but different styles of massive reverb
+ Hidden features are a nice bonus
– Not too many options for “traditional” reverb sounds

The Mercury7 has a space-related name, so it’s no surprise that it’s offering up some galactic-sized ambience. In this case, the reverb space comes in two flavours: Ultraplate and Cathedra. The former has a fast attack but a more understated size and frequency character. That means it still sits as a lush, spongy layer beneath your tone.

Cathedra, on the other hand, has a much more present ‘architectural’ character, rather than Ultraplate’s abstract one. It’s got a slower attack to reflect the size of an actual space. And for further tweaking and balancing there’s a set of low- and high-pass filters.

Pitch-shifting can be applied to the trails, ranging from sub-octave to shimmer sounds, as well as slow drifting up or down. There’s a separate LFO-operated modulation onboard for more wobble, as well as a host of hidden features accessible via the alt-footswitch. The latter also doubles up as a way to suddenly max out decay time, or to engage auto-swell mode for hiding your note’s attack.

It’s perhaps refreshing to see this much power and tweakability applied to a pared-down selection of two core voices. If pedals like the Oceans 12 give you option paralysis, but you’re looking for something more outre than a spring-reverb-in-a-box, the Mercury7 strikes a great balance.

Price: $299/£299 Description: Digital reverb with two modulated and pitch-shifted voices Controls: Space decay, modulation, reverb mix, low- and high-pass filters, pitch-shift mode selector, swell footswitch Bypass: True bypass Mono or stereo: Mono input, stereo output

Anasounds Element Spring Reverb

Anasounds Element Spring Reverb

+ True analogue sounds, no algorithms go near your tone
+ Modular design
– Costly and potentially unwieldy

Speaking of spring-reverb-in-a-box, that’s precisely what Anasounds’ Element Spring Reverb is. More accurately, it’s a spring reverb in a pedal plus one of three sizes of spring reverb tanks, connected via stereo RCA. These tanks contain, well, actual springs – a true analogue way of achieving old-school amp-style reverb.

The pedal, which needs to be connected to one of the tanks to function, offers controls for low and high frequencies, wet-dry mix, as well as overall output. There’s a toggle switch to engage Spring Saturation mode, which overdrives the reverb signal to create a unique distorted reverb tone. But overall, it’s pretty straightforward, putting very few things in between you and the actual spring tanks. As the tanks and the core pedal are separate, you can mount the tank underneath your pedalboard for more space, or keep it on top for easy kicking.

The Anasounds device effectively adds the controls that some players wish their amp’s built-in spring reverb had – and the choice of three sizes may be a bit of a roundabout way to achieve a longer decay time. For analogue purists, it’s spring heaven.

Price: €359 for the ‘premium’ package featuring the pedal and all three spring tanks Description: Analogue reverb pedal that uses one of three outboard spring reverb tanks Controls: Two band EQ, wet-dry mix, output level and switch for ‘saturated’ reverb mode Bypass: True bypass Mono or stereo: Mono

Boss RV-6

Boss RV-6

+ Both ambient and traditional bases covered
+ Versatile I/O and analogue-dry-through
– Not too much deep editing on offer

Fitting into Boss’ famed compact form factor, the RV-6 offers a huge number of features for its size and price. Similar to the Oceans 12, it’s packed with a huge range of core sounds, from spring and plate emulation to modulated and shimmer reverbs. These sounds can be tweaked via level and tone controls, which is great if you just want a variety of sounds straight out of the box.

The RV-6 should also pique the interest of wet-dry-rig enthusiasts for two reasons. Firstly, the pedal remains completely analogue dry-through, so no phase issues should arise if you’re using two amps. And secondly, by using just the ‘B’ input, the pedal outputs a 100 per cent wet signal, meaning it can slot happily into more complicated rigs.

Price: $153.99/£149 Description: Stereo reverb with mode switch for 10 algorithms in total Controls: Reverb mode selector switch, time, mix and tone knobs Bypass: Buffered bypass Mono or stereo: Stereo

TC Electronic Hall Of Fame 2

TC Electronic Hall Of Fame 2

+ Affordable and straightforward
+ One of the most accessible stereo pedals out there
– Not much deep editing without going into TonePrint territory

It may not be the most glamorous or ‘boutique’ reverb out there, but there’s a good reason the TC Electronic Hall Of Fame can be found on the boards of beginner and pro players alike the world over – and it’s not just the price.

In this red box, you get a full range of sounds, all the way from the standard hall, spring and plate emulations to modulated, lo-fi and generally more ambient tones. These 10 sounds are adjusted by decay and tone knobs, as well as a small toggle switch for a long or short pre-delay.

Like the RV-6, the Hall Of Fame is a great option for players who just want a wide range of sounds and a basic degree of tweaking. For more advanced players, there is the option to import algorithms via TC Electronic’s TonePrint tech.

Price: $99/£99 Description: Stereo reverb pedal with multiple modes Controls: Reverb mode selector, tone, level and decay knobs, toggle switch for pre-delay Bypass: True bypass Mono or stereo: Stereo

Strymon BigSky

Strymon BigSky

+ Achingly beautiful ambient tones
+ Stereo is used well to create massive space
– Expensive

The BigSky is another reverb pedal staple, and for good reason. It offers 12 reverb types, with the stalwart spring, plate and hall sound well catered for. Where it’s found the most favour, however, is in its proprietary ambient sounds, such as Bloom, Chorale and, especially, Cloud.

These extremely tweakable sounds are fine-tuned for enormous ambience, creating synthesiser-pad-like drones and airy highs that make full use of the pedal’s stereo support.

With the number of MIDI presets and depth of controls, it’s certainly a reverb for those serious about their sound. It’s the reverb nerd’s reverb pedal, one which you might find yourself lost in. The price tag certainly reflects this, but given how ubiquitous it is across pedalboards everywhere, the Strymon BigSky has certainly earned its reputation.

Price: $479/£449 Description: Stereo reverb with preset support and 12 reverb voices Controls: Decay, predelay, mix, tone and modulation knobs as well s two parameters that depend on the current reverb voice Bypass: True bypass Mono or stereo: Stereo

Neunaber Immerse Reverberator MkII

Neunaber Immerse Reverberator MKII

+ Immersive stereo sounds
+ Intuitive multi-function controls

The second version of Neunaber’s Immerse Reverberator promises, well, more immersion thanks to a few tweaks. Notably, you can now kill your dry signal, and the pedal’s algorithms have been updated for a more spacious sound. Two of the pedal’s knobs vary their function depending on the selected algorithm, resulting in a massive range of sounds to explore and tweak.

The pedal’s stereo support is made full use of, with the algorithms able to convert a mono signal source into stereo. Equally, it will slot happily into a full stereo rig thanks to its stereo ins and outs.

While the pedal’s sound skews more ambient, the traditional sounds are not abandoned, with aspiring, hall and plate reverbs all making a cameo appearance among shimmers and infinite sustain sounds.

Price: $239/£249 Description: Stereo reverb pedal with multiple modes, focusing on ambient depth Controls: Mix and depth dedicated knobs, multi-function pre-delay / modulation / blend and time / tone knobs Bypass: True or buffered (trails) bypass Mono or stereo: Stereo

MXR M300 Reverb

MXR M300 Reverb

+ Present-blending with an expression pedal
+ Healthy balance between ambient and traditional
– Not as many options as some pedals

The M300 is a reverb pedal proudly bearing MXR’s straightforward approach to effects. The stompbox sports a simple three-knob configuration, with the tone knob also allowing you to cycle through six algorithms from plate, spring and room to the more esoteric Mod, Epic and Pad modes – a good 50/50 split of traditional and ambient sounds.

Notably, an expression pedal can be used to blend between two completely different sounds, modifying all three controls at the same time – great for smooth transitions or finding a unique tone.

Price: $199.99/£219 Description: Multi-function reverb with six modes: three traditional and three ambient Controls: Reverb decay, mix and tone Bypass: True or buffered (trails) bypass Mono or stereo: Mono

Free The Tone Ambi Space AS1R

Free The Tone Ambi Space AS1R

+ Focuses on doing a few things well
+ Massive stereo sounds and extensive I/O
– Expensive

Free the Tone has been making waves for its no-nonsense pedals that issue out pristine, as-they-should-be tones. And the Japanese brand’s reverb unit, the Ambi Space AS-1R, does exactly that. What it lacks in features it more than makes up for with stunning, studio-grade reproductions of the four common reverb types: spring, plate, room and hall.

These are the reverb equivalent of the best burger you’ve ever wolfed down. Not the most exciting meal, but it impresses for doing something so simple so well. These four modes are some of the most non-intrusive, natural-sounding we’ve come across in pedal format, from the subtle nuances of the plate ’verb to the lush hall.

Price: $380/£359 Description: MIDI-enabled digital reverb with preset recall and six core voices, four traditional and two ambient Controls: Mix, tone, decay and pre-delay, mode selector, preset footswitch Bypass: True Bypass Mono or stereo: Stereo
