The MXR '78 Distortion is a modern reimagining of classic 1970s hard rock tones, delivering rich, amp-like distortion with a vintage flair. Designed for guitarists seeking a straightforward yet powerful overdrive, this pedal offers a three-knob layout—Distortion, Tone, and Output—along with a CRUNCH switch that toggles between diode and LED clipping modes, enhancing harmonic content and adding brightness to the signal
 
With its analog circuitry and compact, roadworthy design, the M78 excels at producing saturated rhythms and soaring leads, making it ideal for classic rock, blues, and alternative genres. Its dynamic response and tonal versatility have earned it high praise from musicians and reviewers alike
