The MXR FX 77 Overdrive pedal features a classic overdrive circuit that has been updated with a 100 Hz control and a Bump switch to improve performance and versatility. For greater flexibility, we have added a 100 Hz cut and boost control that allows for a more focused equalizer when cut, or a fuller tone when boosted. The Bump switch activates an alternative EQ voice that boosts the lows and mids. Place it in front of the '78 Custom Badass Distortion to get a great amount of amp-like gain structures that will not mask your tone.

This pedal can run on a 9-volt battery, a 9-volt Dunlop ECB003 adapter, or the DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies (not included).
