The MXR M89 Bass Overdrive Pedal brings together volume, tone, and drive controls along with a separate clean control for specific EQ adjustment outside the overdrive, all within an iconic MXR chassis. Delivering warm, broken-up overdrive reminiscent of a hot tube amp, the specific character of the effect is dictated by the user's own dialed-in equalization for profiles from subtle to searing. When you need the low end kicked up a notch, this pedal is on standby.
