Modding my Fuzzy face (HELP Please)

[boldaslove6789]

 Well to make it short:

 I am new to the forum, new to building pedals etc. I am grateful for this site and everybody on it.

Thanks DIY stompboxes!

Anyways, I built this fuzz face and now I want to put a bias pot to balance the transisters ( I think thats what it does)

Where do I put it?


Here's the layout I am using: **Note: I am using a 470 resister instead of the 330 for the negative on the battery**
**Also the BCE leads have to be bent to adapt to this layout for Germs**

i usually leave the 33k alone. try a 10 k or 25 k trimpot in place of the 8.2k resistor, then dial your bias to -4.5v on q2 or to taste by ear.

i also like a 47 uf cap to ground and the mayer mod 2k instead of the1k fuzz pot. if you do this, you might need the 25k trim to get it to bias.

i am a fan of silicon in q1 and a gainy germanium in q2 as well. behaves nicely.

Thanks,
  Can I use a 20k linear trim pot?

  Sure, put a 5k or 6k8 stop resistor [series with the pot], and have between 6k8 and 28k8 adjustability and good 'fine tune type sweep.
  These FF transistors generally bias at 6k8 - 18k thereabouts.
