Classic distortion with creamy sustain.

With the Electro-Harmonix Big Muff Pi Distortion/Sustainer Pedal you get the very same distortion/sustainer effect that countless psychedelic rangers like Hendrix and Santana used for rich, creamy, violin-like sustain. Same as the prized classic effects pedal with low-noise, military-grade transistors. The Electro-Harmonix Big Muff Pi Pedal has its sustain, tone, and volume knobs on the front of the rugged metal stompbox.


  • Classic crunchy distortion
  • Violin-like sustain
  • Volume, sustain, and tone controls
  • Super-tough housing

You know it's going to sound fantastic. Why wait? Call us or click to order now.
