Happy Fuzz Friday, all! Here's a cool silicon Tone Bender style fuzz from Solid Gold Fx. Aside from using silicon transistors, the first stage is a JFET. When the switch is closed it adds in a 4.7uF input cap in parallel with the 330pF input cap. You could replace the switch with a B100k pot (lug 1 to Sw1 pad, lugs 2-3 to Sw2 pad) to blend the two values. Set the trimmer to 4.5v for the JFET and adjust by ear as needed.
