MXR Bad Ass Overdrive (MXR M77)

The MXR M77 Custom Badass OD is a thick and juicy overdrive with control over volume, gain and tone in addition to a fixed frequency 100hZ boost/cut knob that allows you to tighten up (cut) or beef up (boost) the tone to your desired sound. Finally there is a 'bump' switch that pushes the low mids for super beefed up tone.


Next up in the MXR Custom Badass line is the Modified Overdrive—a classic overdrive circuit with modern modifications for improved performance and versatility

For added flexibility, we’ve added a 100HZ cut and boost control that allows for a more focused EQ when cut, or a beefier tone when boosted. The Bump switch engages an alternate EQ voicing that boosts the lows and mids. Put it in front of the '78 Custom Badass Distortion for a slew of amp-like gain structures that won't mask your tone.
