This return of the tremolo effect to the MXR line combines a full historical range of masterfully tuned tremolo styles with a host of features to satisfy the performance needs of today's discerning players. With the MXR M305 Tremolo effects pedal, you have access to the most iconic tremolo voicings ever created. A huge factor in the sound of any tremolo effect is the shape of its modulation waveform, and the M305 Tremolo offers waveshapes and tremolo modes based on classic tremolo circuits from '60s tube amplifiers, photocell circuits, and, of course, the acclaimed MXR M159 Stereo Tremolo effect. Tap into the psychedelic Harmonic tremolo mode for phaser-like modulation. Complete with a multiuse jack for tap tempo, expression control, envelope control, or stereo audio output, the MXR M305 Tremolo is fit to be your do-it-all tremolo effects solution.

The MXR Tremolo's six tremolo waveforms represent classic and iconic sources of the effect as well as new sounds concocted by the MXR design team. First, the MXR style recreates the organic sound and pulse of the much beloved M159 MXR Stereo Tremolo. Next, the Bias style takes after the lush, power-soaked compression of tremolo effects that came equipped on early 1960s tube amplifiers. The Revo style, an original innovation, turns the optical tremolo waveform backwards for more exaggerated peaks and valleys. The Opto style emulates the smooth pulsating tremolo generated by photo cells in many popular amplifiers. Inspired by an iconic outboard effect, the SQR setting produces choppy, super pronounced tremolo. Finally, the Harm style recreates the trippy, phase-like tremolo produced by certain rare vintage amplifiers. 

Getting incredible sounds from the MXR Tremolo right out of the box is simple. Speed, Gain, and Depth controls set the rate, volume, and intensity of the selected tremolo effect, and cycling through the six styles is as simple as pushing the Gain knob. For advanced technicians of tone, a bevy of features await—from stereo operation to tap tempo and expression pedal functionality to envelope tremolo, which makes the response of the effect sensitive to your attack. 

These and other features come in a single MXR housing so that you can put a wide variety of intriguing, well-crafted tremolo waveforms on your board with no overcrowding.
