MXR M305 Tremolo Instrument Effects Pedal

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.

Six tremolo modes, from subtle to psychedelic

  • MXR: Re-creates the vibrant, rich pulsations of the classic M159 Stereo Tremolo
  • Bias: Based on the "lush, power-soaked compression" heard in '60s tube amplifiers with built-in tremolo circuits
  • Revo: Based on an optical tremolo waveform, reversed for more exaggerated peaks and dips
  • Opto: Based on photocell tremolo circuits found in vintage amps, with a lush, smooth character
  • SQR: Square-wave tremolo for choppy, pronounced tremolo
  • Harm: Based on the harmonic tremolo found in vintage amps, for trippy phase-like modulation

Multipurpose jack for advanced functionality

In addition to the In and Out jacks on the MXR M305 Tremolo, you'll also find a CTR jack with an adjacent toggle switch. With the switch set to Tap/Exp, you can connect a tap tempo switch or an expression pedal for additional control options. Or, set the toggle to Audio to convert the pedal to stereo output.
