Tri-Knob Fuzz

The pedal that inspired Tri-Knob Fuzz was a transistor-based unit, originally popular with lead guitarists searching for ever-higher gain in the 70s. It shone again in the 90s grunge rock scene, probably pushed further into woolly grind than its makers would have ever anticipated.

After being inspired by discussing tone with Jimi Hendrix in the studio, Electro-Harmonix owner Mike Matthews designed the pedal that would launch his company into history and become one of the best-selling distortion effects of all time—the Big Muff Pi. Like the original, our effect employs a three-knob configuration and when combined with the True-Z input, you get an extremely accurate emulation.
