MXR Bass Synth | MB301

Turn your bass into a filthy funk machine with the MXR Bass Synth.

It serves up intergalactic grooves and vintage analog-style vibes with a range of monophonic synth tones that call back to hits from Stevie Wonder, Michael Jackson, Parliament Funkadelic, and more.

Designed with low-end professor and tone connoisseur Ian Martin Allison, this powerhouse of a pedal offers thunderous sub-octave, expressive envelope, and lush modulation effects with killer tracking and sustain.

FUNK IT UP
Dig into your groove with a full, player-friendly suite of controls to shape every detail of your bass synth tone.

The Sub Mix knob sets how much of the sub octave is blended with the main synth signal so that you can go as fat and low as you want.

The Mod knob brings shimmering liquid tones, from subtle, musical motion to bold, mind-bending pulses—while the Envelope knob sets the filter response from rubber band bounce to slow, syrupy sweeps.

Mix, Cutoff, and Resonance knobs help you dial in the perfect tone and feel for your setup—blend dry and wet signals, set filter cutoff frequency, and boost that frequency for extra punch.
