Designed with low-end professor and tone connoisseur Ian Martin Allison, the MXR Bass Synth is a powerhouse of a pedal offers thunderous sub-octave, expressive envelope, and lush modulation effects with killer tracking and sustain—plus all the features you need to shape every detail of your tone.

This pedal requires a 9-volt (330 mA) center-negative power supply and can be powered by the Dunlop ECB003 9-volt adapter or the MXR Iso-Brick, the Iso-Brick Pro, and the Iso-Brick Mini Power Supplies. This pedal cannot be powered by a battery.
