MXR MB301 Bass Synth Effects Pedal

MXR MB301 Bass Synth Effects Pedal

The MXR MB301 Bass Synth delivers an incredible range of powerful, vintage-inspired synthesiser tones, transforming your bass guitar into a versatile synth machine. Developed in collaboration with renowned bassist Ian Martin Allison, this feature-packed pedal combines thunderous sub-octaves, expressive envelope filtering and lush modulation to create everything from classic funk and disco bass sounds to modern, aggressive electronic textures.

Featuring an extensive range of sound-shaping controls, the MB301 allows you to customise every aspect of your synth tone. The dedicated Mix and Sub Mix controls let you blend your original bass signal with the main synth and sub-octave voices, while the Cutoff and Resonance controls shape the character of the filter. Three selectable oscillator waveforms provide additional tonal variety, and the Voice button introduces harmonically tuned oscillators for more complex sounds.

With eight onboard presets inspired by iconic synth bass tones, advanced editing capabilities and excellent tracking and sustain, the MB301 offers an impressive range of creative possibilities. Whether you're chasing classic funk grooves, thick electronic bass lines or experimental synth textures, the MXR Bass Synth delivers serious versatility for stage and studio use.
