The MXR M89 Bass Overdrive is a versatile, all-analog pedal designed specifically for bass players who want added grit without sacrificing low-end power. Delivering warm, tube-like overdrive, this pedal allows you to dial in everything from subtle breakup to aggressive, punchy distortion while keeping your core tone intact.

A standout feature of the M89 is its Clean control, which lets you blend in your unaffected signal alongside the overdrive. This ensures your low-end remains full and defined—something many traditional overdrive pedals struggle to maintain on bass.

With intuitive Volume, Tone, and Drive controls, the Bass Overdrive offers a wide range of usable tones suitable for rock, blues, and modern styles. Whether used as an always-on tone enhancer or for more aggressive drive, it delivers a natural, musical response that sits well in any mix.

Built in MXR’s rugged compact enclosure with true bypass switching, the M89 is ready for the stage or studio, offering reliable performance in a pedalboard-friendly format.
