DESCRIPTION

Turn your bass into a funk-fueled synth machine. The MXR Bass Synth delivers gritty, vintage-inspired monophonic tones that channel the spirit of Stevie Wonder, Michael Jackson, and Parliament Funkadelic. Co-designed with Ian Martin Allison, it dishes out massive sub-octaves, expressive envelopes, and rich modulation with spot-on tracking and sustain.

A player-focused layout gives you full control over your sound. Sculpt the low-end with Sub Mix, add movement with Mod, and shape filter response with the Envelope knob—from tight, rubbery snaps to smooth, sweeping curves. Mix, Cutoff, and Resonance controls let you fine-tune your tone, while the Voice and Shape buttons unlock harmonically complex synth textures with triangle, sawtooth, or square waveforms.

Want to skip the setup? Eight built-in presets inspired by legendary tracks like “Thriller,” “Chameleon,” and “Sledgehammer” give you instant access to iconic synth bass tones. Just hit the Preset button and play.

For advanced users, the MXR Bass Synth also includes options for stereo output, external switching, and expression pedal integration, allowing for deep configuration and on-the-fly control.

Whether you're laying down grooves on tour, holding the pocket at church, or recreating hits on stage, this pedal brings instant synth bass magic to any rig. Plug in and get down.
