Fuzz Face Grounding Issue... I Thought...

[GüdPedals]

Greetings, all!

I have a circuit that's essentially an NPN Fuzz Face with a Baxandall EQ slapped on plus a few other mods. I've built it on perf board a few times so I know it works, but I recently decided to order some actual PCBs for it and they seem to have what I thought was a grounding issue (very low output volume, so I assumed it was grounded somewhere it shouldn't be). I built out two of them and had the same issue with both.

After measuring some voltages to ground, the only discrepancies I found were a) the collector voltage on the second transistor is high(almost the full 9V, should be 5-6V), and b) the voltages from all 3 lugs of the Fuzz/Gain pot are the same(around .8V). Lug 1 should be basically nothing, as it is tied to ground, and lug 2 should vary with wiper position, but doesn't. So now I'm thinking maybe it's a misbias that's killing the gain, but that doesn't make sense, as I have built it before on perf and breadboard with success.

I've tried recreating the problem on breadboard to no avail. Was hoping one of you fine folks would have some ideas.

Thanks!

Enormous amount of ideas..

Could you plz help us to reduce them down to a controllable level by posting schematic & PCB layout..??

Obviously it isn't.
