FUZZ FY-2

Creating a fuzz tone basically involves slicing off the peaks of the signal, something which engineers call "clipping". In it's simplest form, a fuzz circuit would make the clean sine wave signal from your guitar look like a square wave, but most fuzz circuits go beyond merely clipping the signal, and perform some other fancy waveshaping as well. But, the heart of any fuzz is the circuit that clips the signal.
