MXR M78 Custom Badass '78 Distortion – Hot-Rodded Classic Distortion
The MXR M78 Custom Badass '78 Distortion delivers the raw, saturated power of late-'70s hard rock in a compact stompbox. Based on a classic distortion circuit and hot-rodded for modern performance, this pedal produces everything from crunchy rhythms to soaring, singing leads with rich harmonic content and dynamic response. It's designed to sound like a stack of cranked tube amps—without the weight or volume.
The CRUNCH Switch – Two Distinct Voicings
At the heart of the M78 is the CRUNCH switch, which toggles between two clipping modes: classic diode clipping and more aggressive LED clipping. This simple switch dramatically changes the pedal's character, adding extra gain, harmonics, and a more open, dynamic feel. It's like having two distinct distortion pedals in one.
Simple, Effective Controls
The M78 keeps it straightforward with just three controls: Output, Tone, and Distortion. The Tone control uses a Tilt EQ design, offering ±4 dB at 100 Hz for quick tonal shaping. Whether you need a subtle grit or a full-on distortion assault, dialing in your sound is fast and intuitive.
A True Pedal Platform
The M78 excels as both a standalone distortion and a pedalboard cornerstone. Its amplifier-like response means it works equally well into a clean channel, a slightly broken-up amp, or an already overdriven front end. Stack it with overdrives or boost it with a clean boost for even more tonal possibilities.
Built to Last
Housed in a rugged metal chassis with top-quality components, the M78 is built for the road. It runs on a standard 9V battery or an optional Dunlop ECB003 9V adapter, DC Brick™, or Iso-Brick™ power supply.
