A tremolo effect consists of amplitude modulation, which cyclically raises and lowers the signal level. Guitarists usually utilize a pedal to get this effect, although a similar effect may be achieved by rapidly adjusting the volume knob on the instrument or amplifier. However, the best tremolo pedal is able to create many variations of tremolo sound (chops, wobbles, purrs, etc.).

The tremolo pedal is one of the oldest guitar pedals ever. The first one appeared on the market in 1941. However, before its appearance, the tremolo effect was reached with the help of special amps which were supplied with the built-in feature that automatically modulated the volume.

The tremolo effect is used for the creation of some dramatic musical effects. It can be heard in the musical compositions of such popular artists like Johnny Marr (The Smith), Link Wray, Marc Ribot, Duane Eddy, and Jonny Greenwood. As for modern music, the tremolo effect is used in Green Day’s “Boulevard Of Broken Dreams”, for example.

Tremolo pedals are still among the most popular nowadays since they are inexpensive and easy to use while having a major impact on the tone of music.

It can be tough to understand what you should look for when choosing the best tremolo pedal.

To shed more light on how the tremolo pedal works, there is also an informative buyer’s guide which will explain about this device.

Tremolo Pedal Reviews



The present model from Fender is a reverb tremolo pedal that can produce both tremolo and reverb effects. The pedal comes in 8 different colors to suit your preferences: three different hues of green, two different shades of blue, silver, grey, and black.

It has 6 control knobs. The Level knob adjusts the tremolo output level. The Rate knob allows setting the speed. The Depth knob allows adjusting the intensity of the tremolo. The Tone knob controls the number of high frequencies. The Blend knob controls the amount of reverb. The Dwell knob adjusts the amount of reverb sustain.

Except for these knobs, this tremolo pedal also has two three-way toggles. The first one allows choosing between three different tremolo voices: Opto (for optical tremolo), Bias (for tube tremolo), and HM (for a more harmonic tremolo sound). The second one offers three different reverb voices: ‘63 (to get similar to Fender’s standalone Reverb Tank sound), ‘65 (for classic blackface-amp reverb sound), and Plate (for splashy reverb sounds that are great for studio recordings).

A path switch is located on the top side of the pedal and allows you to select the order in which the tremolo and reverb effects are applied. Two footswitches to control the amount of both effects are located on the bottom part of the face panel. The tremolo effect can also be controlled with a tap tempo.

The pedal also has two LED indicators that show the on/off status of the reverb and tremolo effects (blue for tremolo and red for reverb), the rate LED indicator (located between Rate and Depth knobs) which blinks at tremolo tempo.

There are two stereo inputs and outputs. This model is supplied with a standard center-negative 9V DC jack.

Despite the number of controls, the pedal is only 3.75 x 4.9 x 2.5 inches so it fits in the palm of your hand and weighs 1.2 lbs.


  • There is a LED kill switch with the help of which you can turn off all the LEDs if they bother you.
  • It’s possible to either mix the tremolo and reverb effects or use them on their own.
  • The right and left input jacks are very multifunctional: they work with any guitar (electric, bass, acoustic), keyboards, and other instruments.


  • The knobs are too small, being located too close to each other.
  • The pedal may seem not very responsive.

Buyer’s Guide

Working Principles of Tremolo Pedal

As soon as you turn the tremolo pedal on, it creates a wave: sine, square, or triangle one. Some pedals offer only a certain type of wave, and the others give the opportunity to create multiple types of waveforms. Its circuitry begins to create a wave carrier signal, changing your signal’s amplitude. In simple words, the volume reduces to a minimum and then becomes intensive again.

Today, there are a lot of circuits that are able to create a tremolo effect. The pedal may vary the amplitude of the sound wave, producing a tremolo effect, since one of them is dependent on the voltage-controlled amplifier. Such a circuit is really simple, reliable, and stable.

The modern tremolo pedals (and handmade pedals) as a rule, use a low-frequency oscillator (LFO) circuit which allows for a compact size, wider functionality, and cheap price. It usually consists of high and low pass filters. To create a tremolo effect, it changes the signal’s phase. As the name implies, the low-frequency oscillator is designed to work at low frequencies, so the range of preset values usually lies in the range from 0.1Hz to 10Hz. Its peak values affect the volume while the values in between affect the speed.

The main purpose of the LFO is the wave formation.

Types of waveforms

The sine wave is one of the simplest ones and was used in the first tube tremolo pedals. This type of wave doesn’t have any harsh lines, so it has a soft, subtle, and smooth sound. It’s created thanks to the modulation of transistors or power tubes. In some tremolo pedals, this form can be blurred, resulting in a not so pronounced tremolo effect.

The square form is a modern type of form and it sounds quite tough and abruptly as the sound may completely disappear at some point. The square wave creates a pulsating tremolo, producing a dramatic effect. At high-speed value, it reminds the sound of helicopter chops.

The triangle wave is one of the classic ones. The triangle shape means that both peaks and lows will be very pronounced and it doesn’t matter how you play. It slices through the music, creating an unusual effect. The triangle wave is something between the sine and the square wave. However, it’s not as blurry as a sine wave and not as sharp as a square wave. The triangle wave was used in first optical tremolo pedals, where it sounded smother. In the modern pedals, it’s more pronounced.

There are several additional waveforms in addition to these three, although they are not as frequent. For example, the sawtooth wave: it reminds the triangle wave, but the peaks and lows are much more pronounced as the ups and downs occur more often. There is also a sharkfin type of wave, which, basically, the same as the sawtooth.

Rate and depth controls

The rate control is responsible for the speed at which the sound changes its volume and it always requires some fine tuning as it should match the tempo of the song you are playing. This is one of the main tremolo parameters, so it’s present in almost all the pedals. In some of them, the frequency of volume changes can be set with the help of tap tempo.

The depth control allows adjusting the depth of the effect: how quiet the signal will be between the peaks of the wave, from light flicker to complete silence. Lower depth values help create a more subtle effect while higher values are more dramatic.
