This used MXR M89 Bass Overdrive pedal is in great condition and delivers warm, gritty overdrive specifically voiced for bassists. Designed to preserve low-end clarity while adding punch and aggression, the M89 features separate Clean and Volume controls for blending your dry signal with saturated drive, along with Tone and Drive knobs for shaping your sound. Its true bypass design ensures no loss of signal when disengaged. Housed in a rugged metal enclosure, it's built for the rigors of gigging. Powered by a 9V battery or optional adapter (not included), this pedal is perfect for adding depth and character to any bass rig.
