Hey all,
I just ordered a Fuzz Face and Rangemaster PCB from General Guitar Gadgets and the GE Transistors from Smallbear.
Smallbear sends out resistors with the GE Transistors that are recommended to use.
The problem is, I don't know which ones to swap out.
Has anyone done this?

Rangemaster Layout:

Smallbear resistors:
56k
3.9k

Fuzz Face:

Smallbear resistors:
30k
680ohms
9.1k
120k

The 56k will replace the 68k (R2)

The 3k9 is already on the layout.

The 30k replaces the 33k (R2)

The 680 ohm replaces the 470 ohm (R4)

The 120k replaces the 100k (R3)

The 9k1 wont need to be used, as you have a 10k trimmer.

Replace the 68K resistor on the RM with a 100K trim pot. Bias the transistor to your taste.
