Dunlop · pedal

The MXR M77 Custom Modified Badass OD is an overdrive pedal from MXR by Jim Dunlop, a modernized version of the classic MXR circuit designed to deliver touch-sensitive, dynamic overdrive at a wide range of gain settings. The M77 is built around a warm, musical saturation character inspired by vintage MXR designs, with added EQ controls that extend the tonal palette beyond the original stripped-down format. It delivers compressed, warm overdrive suited to blues, classic rock, and hard rock applications and has been used by players who want a rugged, road-ready overdrive with recognizable MXR tone character.
