John Frusciante’s Electro Harmonix Big Muff Pi
This pedal seemed to have directly replaced the “Black Russian” Big Muff Pi that John was seen using on the Californication tour. The US version of the Big Muff Pi was then used during the By The Way tour, and likely during at least a part of the Stadium Arcadium tour.
