From the post
Another from the man, the myth, the legend Joe Gagan. Not much to out there as far as info go, but it's another fuzz, based on the fuzzface with a bunch of tweaks. The only change I made is i removed the test switch, since I bought anyone wants to wire up a voltmeter in the pedal.
Here's Joe's notes on setting up the effect:
• Set the bias pot to 0
• Bias Q2 using the trimmer to -4.2V
• When you change the bias pot it should max out at -7.4V
Note: I put it in the notes, but Q2 should be a high gain PNP Germanium transistor
