The MXR Custom Badass 78 Distortion roars with huge amp stack tones and old school distortion. We 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.
