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.
