Silicon Fuzz Factory Schematic. ZVex has just released a limited-edition Silicon Fuzz Factory 7 Mod. Fuzz Face Ready-For-Transfer Printed Circuit Board Layout For use only if you are a complete DIY person who wants to etch and drill your own PCB.
A lot less saturated it could be described as softer warmer and rounder. Mitchell likes silicon 2N3904s in this circuit. ZVEX Silicon Fuzz Factory 7.
This follows the stock NPN silicon version with BC108 transistors.
Germanium only unless you have the time skill and patience to play with all the values in the circuit to get the best sound from silicon transistors PNP vs. The new transistors give the Silicon FF7 a. The pedal uses a double PNP transistor stage and a feedback network. Youre not using the right transistors and although you can use silicon transistors to check that a circuit works theres no way I would expect the results to sound like an original Fuzz Factory.
