*** HELP arbitor fuzzface ***

yup its me agian i cant get this damn thing working! The fuzz pot on my fuzz face doesnt change the fuzz level ive swapped out the pot for a different one and that didnt fix it. Im using ge transistors/and the resistor values given from smallbear their are no solder bridges or anything its very clean
ives checked the grounds and all the wireing a zillion times im out of ideas with this thing.

I finished building the fuzz face tonight and it sounds pretty nice, even with the crappy SI transistors I used.  I have the same problem though,  my fuzz control does nothing to alter the tone.   I wonder whether the fact that my circuit is biased for GE transistors has any bearing on whether the fuzz control works or not?  But then that doesn't explain the problem the other guy has as he has GE transistors.  Could someone here who knows what they are talking about enlighten us?

Thanks

The fuzz pot on a working FF does not clean up the distortion when it is turn down. In fact the sound gets muddy. That's why many people replace the pot with a fixed resistor and use the guitar volume. Also a rev log pot works better.
But I guess your pot is doing nothing. The cap should be soldered to the center lug of the pot and to gnd. If you are using positive gnd (pnp ge or si) gnd is the +9v and the (-) side of the cap should face to the pot.

BTW, re post your readings.

 Q1C still isn't hooked up to Q2B according to those readings.
