The MXR M77 Custom Badass Modified O.D. features a classic overdrive circuit that's been upgraded with a 100HZ control and a Bump switch 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.
