Thanks for all the tips guys.

First off sorry I've been taking so long to respond to any of these. I've been busy as hell lately. Anyways I checked the pot resistances and that turned out pretty interesting. One of the 10k pots is only reading 5k and one of the 5k pots will sometimes steadily read around 300k but also sometimes read 7M and start decreasing slowly. I think  I have an extra 5k and 10k pot laying around I'll look into replacing those.

I suppose they could be backwards but I checked the wiring several times. The pot lugs are wired from left to right 1 2 3 when looking at one straight on correct? Like the picture in this thread...

The voltage at lug 3 of the stab is reading 1.3mV

Thanks for the help Jacob. I just read your thread and watched your video on how to use and build the audio probe. I'm gonna have to build one. Seems like a pretty useful tool.

I'm just using a one spot 9v supply I'm getting a reading of 9.4 volts at the 9v node and at the source. So I don't think that's the problem. Hopefully I'll be able to narrow it down after I build the audio probe.

Hey guys,

I recently built a fuzz pedal using the zombii pcb. The pedal worked for a little bit and then stopped working correctly. When the pedal is on the output is real quite and not fuzzy at all.

I checked the transistors they seem to be alright. However the voltage drops across the germanium transistors were .136 volts and I read somewhere that the drops across the transistors should be .45-.9 volts. I'm not sure if that specification includes germanium transistors though.

The only other problem I encountered was when I checked the capacitance of C2. When the capacitor was soldered to the board the reading was not 100nF it was something really small. When I took C2 off the pcb and checked the capacitance it was right around 100nF.

Any ideas? Any help is greatly appreciated.

Thanks
