Solid Gold FX Rosie

 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.

  1. It Works! Sounds pretty cool with BC549s. I didn't have 239s. I'll audition others later, Woohoo Friday night transistor swapping!
