The Fuzz Face also attracted a number of clones even in the Golden Age. Due to these tolerances in gain varying so wildly, it’s very rare that you’ll ever find two transistor fuzz pedals that sound identical unless the creator has painstakingly used the exact same values for their transistors across all their pedals. It is important to thoroughly read all instructions before you start building. Sometimes Hfe is not important, your ears will tell you this. Here is the cross reference: If you have a common power supply to power your pedals, the negative ground version will work with your other pedals on a common power supply. I had also seen much written about the complexities of proper biasing and transistor selection, which made the Fuzz Face a bit more more daunting for me, still a relative novice. Wiring for PNP transistors (Positive ground): It is stronly suggested to power the PNP Fuzz Face only with a 9V battery and avoid the DC connector. 2.2 Components Part List / Bill of … I've owned and tried quite a few others through the years but the only one I still have is the NPN.
