MXR Bass Synth

The MXR Bass Synth, developed in collaboration with Ian Martin Allison, is a powerful pedal for bass players who want to take their sound to the next level. With deep sub-octaves, expressive envelope filters, and rich modulation, this pedal delivers a massive, modern synth bass tone that responds directly to your playing style.

Thanks to excellent tracking and long sustain, every note stays tight and controlled, even in complex passages. Whether you're looking for subtle textures or a fully pronounced synth sound, this pedal gives you all the tools you need to shape your tone in detail.

Note: the MB301 only operates with a 9-volt (330 mA) center-negative power supply and cannot be powered by battery.
