Help with Fuzz face breadboard biasing

[Henry89789]

I have been reading here about building a fuzz face on a breadboard to get the resistor values that go with a transistor in order to properly bias the transistor.  So I built a FF on the bb and was able to get the voltage on Q2C down to (it was higher with 8.2K and the 10k trim pot.  )  -5.9 by substituting the 8.2k with a 6.8k; and by substituting the 33k  with a 26.7.  Which way should I go from here? Keep reducing the values of these two resistors? Or change something else?

I also have a question about the fuzz face on the bread board. The circuit seems to work. The pots also work. The volume pot reduces volume but the fuzz pot only seems to increase gain but very minimal fuzz effect. I don't think it is the transistors because they sound good in a FF pedal I built. I have reviewed the connections several times, and I have bult four FFs and they all work. So I don't understand why it works and sounds good in a soldered pedal but not on the bb. Any ideas on what the problem may be? Thanks.

A stock germanium Fuzz Face? Depending on the type of transistor, a 10K trimmer in place of the 8k2 will probably be all you need. You posted "8k2 and the 10K trim pot" which would be a minimum resistance of 8K2 to a maximum of 18k2. Just a 10K trimmer is fine - you do not need both. Leave the 33K alone for now.

The traditional approach dictates making the collector of Q2 hit 4.5V. It is a good starting point but I prefer to tune each transistor by ear with a trimmer or leave a low value resistor in series with a standard ~5K-10K pot and use the tandem as an external bias. I have biased FF under and over 4.5V - it depends on the transistor and the sound/feel you like.

Again, the search feature on this forum would answer that question for you rather quickly.

Check your bread-boarded circuit for mistakes.
