A hot-rodded classic circuit that roars with huge amp-stack tones and old-school distortion.
The MXR Custom Badass '78 Distortion roars with huge amp stack tones and old-school distortion. MXR took a classic distortion circuit and hot-rodded it to deliver over-the-top, soaring leads and rich, saturated rhythms. With only three knobs, dialing in a badass tone is a cinch. Engage the CRUNCH button to boost the harmonic content of the distortion. Under the hood, this high-performance machine features top-notch circuitry and hardware meant for a lifetime of use.
This pedal features a hot-rodded classic circuit that roars with huge amp stack tones and old school distortion with a Crunch switch to boost harmonic content.

The Long Story
The MXR Custom Badass '78 Distortion is a factory-modded pedal that roars with huge amp stack tones and old school tube amp-like distortion.
We took a classic distortion circuit and hot-rodded it to the next level for over-the-top soaring leads and rich, saturated rhythms. With only three knobs, dialing in Badass tone is a cinch. The CRUNCH button allows you to choose between two different modes of diode and LED clipping, boosting the harmonic content of the distortion.
The '78 Distortion's wide open amp-like sound sounds great whether it's in front of a clean amp, a slightly dirty amp, or a full on overdriven amp. Under the hood, this high performance machine features top notch circuitry and hardware meant for a lifetime of use.
