The Electro-Harmonix Big Muff Pi is the pedal that started it all. The Big Muff Pi is the distortion pedal countless musicians, including Hendrix and Santana, relied on for its rich, creamy, violin-like sustain. A timeless piece, the Electro-Harmonix Big Muff Pi has been defining the sound of rock guitar for the past 30 years.

Like the legendary Big Muff Pi of the '70s, the Electro-Harmonix Big Muff Pi reissue has three controls that let the player dial in the finest harmonic distortion/sustain ever produced. The Big Muff Pi's Volume control adjusts the output level. The Sustain control optimizes the long sustain with just the right amount of harmonic distortion, and the Big Muff Pi's Tone control provides a range of sounds, from warm bass to crisp treble. From Pink Floyd to the Chemical Brothers to Korn, everyone wants a piece of the Pi!
