Farmer Factory Effects // Sherwood (Carlsbro Fuzz Tone) 

Based on the Carlsbro Fuzz-Tone, the circuit is built with three germanium transistor Mullard OCP71.
The ATTACK control varies the gain a little, but to me it's more of a timbre control.
Footswitch pcb with voltage inverter and trimmer to control imput level.
Works only with an external power supply.
