Piggyback Pair

Germanium transistors are becoming more and more scarce and the ones that you do find aren't great options for the classic fuzz circuits. If only there was a way to use silicon transistors, both cheap and readily available, to simulate/emulate germanium transistors. Well the Piggyback method of tying two silicon transistors together does exactly that. It also allows the gain of the end transistor to be dialed in via trim pot. There are a few pedals on the market that use this method to produce their tones but it's really not that common. Try it out.
