The MXR M78 Custom Modified OD, also known as the Bad Ass Modified OD, is a vintage-voiced overdrive from MXR by Jim Dunlop based on the 1978 MXR Distortion Plus circuit with additional Tone and Filter controls added to increase tonal flexibility. The 1978 vintage Distortion Plus is known for its warm, smooth clipping character and distinctive compressed saturation that works well into an already-driven tube amplifier. The M78 extends the original circuit with front-panel EQ control that was not available on the vintage unit, allowing players to shape the midrange and frequency balance without requiring external pedals. It bridges the original vintage MXR sound with modern usability.
