The MXR Bass Overdrive is a one-of-a-kind design that produces a warm, tube-like overdrive. In addition to the conventional Volume, Tone, and Drive settings, this pedal has a Clean control that allows you to combine a pre-set EQ clean signal with the overdrive signal for a beautiful beefy bass overdrive.


The MXR Bass Overdrive, also referred to as the M89 is part of an increasingly diverse group of overdrive/fuzz pedals in the Bass Innovations line. The MXR M89 Bass Overdrive pedal provides the thick and gritty punch you're looking for, as well as the control you'll need to make it work with the rest of your bass setup. The M89 Bass Overdrive is designed specifically to handle the increased low frequency of your bass, and it grows beefier the harder you pound it in, never becoming anemic like a guitar overdrive pedal. With just four, easy to comprehend, knobs, the Bass Overdrive is easy to use even for beginner players. It also exhibits good touch sensitivity. The four knobs on the box include controls for Clean (which blends in a tuned clean signal – comprised mostly of the lower frequencies – with the overdrive signal), Volume (which controls the overall output volume), Tone (which adjusts the color of the overdriven signal), and Drive (which controls the amount of overdrive). 

The M89 Bass Overdrive delivers burly overdriven tones with a Clean control to blend in a pre-set EQ clean signal. The Clean control lets you blend in as much clean sound as you like, allowing you to preserve your transients and fill out the bottom end. The sound of the pedal is best described as dark and aggressive. 

The M89 Bass Overdrive has an attractive grey finish on the case, with a metallic sheen and a hint of sparkle to the paint and a bright white LED indicates when the overdrive is engaged. This pedal can be powered by a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies (not included).
