John Frusciante

An Electro-Harmonix Big Muff Pi can be seen in this picture of John Frusciante's pedalboard. Electro-Harmonix also confirms the use of the Big Muff Pi.

In addition to the English Muff'n, John has also toured and recorded with the Micro Synthesizer, Big Muff Pi (both USA and Russian), POG, Metal Muff, HOG, Holy Grail, and Deluxe Electric Mistress. That said, I'm sure you fru-heads are still going to email and tell me what I left out.

In an April 2004 issue of Guitarist magazine, John Frusciante talks about using the ZVex Fuzz Factory pedal on his studio album Shadows Collide with People. He says, "Well, there's the Fuzz Factory. That guy (Zachary Vex) makes really interesting effects and he handpaints them himself. The song Water has that crazy guitar sound at the end of it and that's just me playing right-hand finger harmonics and that's the sound that came out of the thing!
