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.

1. Source Audio Vertigo

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

Versatile pedal
Shape control is ace

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

Rugged

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.

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.

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

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

Best tremolo pedals 2019: Electro-Harmonix Super Pulsar

(Image credit: Press Material)

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

Great for creative guitarists
Plenty of control
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.
