Deluxe Big Muff Pi

Fuzz / Distortion / Sustainer

Legendary fuzz with added features like a Bass Boost, Noise Gate, and adjustable Mids section for the most versatile Muff ever!

Long revered for its sweet singing tone and violin-like sustain, the classic three-knob Big Muff Pi has helped define the sound of rock guitar for over 50 years. Now, we’ve added some extras for those who crave more sound shaping control. The EHX Deluxe Big Muff Pi delivers all the classic sounds of the original NYC Big Muff Pi, plus more.

Added footswitchable Mids sections boosts or cuts an adjustable mids frequency for added definition or massive scooped tones. Add an optional expression pedal and turn the Deluxe Big Muff into an extreme fuzzed out wah!

The Attack control preserves pick attack with an enhanced version of your dry signal while the Bass Boost adds rumble at higher tone settings. The Gate removes unwanted hiss for a more dynamic performance.

This is the most versatile Big Muff ever!
