Of course...... Zachary should have one.

It’s a fuzz factory using 50s transistors, adding a passive tone control (I wonder if the tone control is like the woolly mammoth), a switch to bypass the tone control and and 9 position switch for the fat feature (I guess switching the original 10nF capacitor for 8 more differents values).

Is someone brave enough to draw a eschematic to start testing? :hmmm:

:horsey: I will try one tomorrow :scratch:

the switch should be DPDT ON-OFF-ON so you can go back to the stock fuzz factory. everything on here is designed so you can go back to the fuzz factory. I did not want to build something that could not replace my old 7 knob fuzz factory that I sold and ZVEX copied exactly 3 years ago. the output volume is doubled without adding noise from extra gain stages. the only thing I am a little unsure about are the values for C7 and C4. if you want to do the tone control like the official zvex 7 knob, you should leave tone pin1 disconnected or maybe just move the tone control to the output jack like a guitar. I am finishing up the pcb design right now if anyone is interested PM.

comments and suggestions welcome.
