The StonegateFx Транзистор (Transistor in Russian) is a hybrid germanium/silicon fuzz face. It utilizes a vintage NOS soviet germanium transistor as well as a BC108-b metal can silicon transistor for a great vintage sound. It can be put anywhere in the chain with its internal pickup simulator and in/out buffers. The pickup simulator is basically a small audio transformer that mimics the impedance of a guitar pickup. That way the circuit "sees" a guitar pickup and sounds as if it is first in the chain. With the additional input/output buffers you don't have to worry about other pedals affecting the fuzz's tone!
