PCSC - I knew this would be a tough one...

Pulling R33 removes the distortion path -- i.e. nothing from the overdrive section reaches the mixing stage.

Pulling R34 removes the clean side from the equation.

Since you're getting clean signal at the output jack, it looks like your clean side is working. It's your distortion side that's conking out. Reconnect everything as before, and start following the distortion path. You'll want to probe pins 3, 1, 5, and 7 (and 6), as well as lug 3 of the dry mix pot, to see where you're losing signal.

Before you go any further, though, I'm going to suggest a complete reflow on all your solder joints, and you may want to remove and then socket Q1 -- there's a small possibility that the transistor was damaged by static, and there is no protection diode in this design for the MOSFET.

Sorry, to clarify, I am getting unchanged, or still overdriven tone at the output with R33 pulled. With R34 pulled, I get no sound at all at the output.

I was able to play with this some more tonight and took voltages but.. I feel stupid. When using Jon's advice with the checking R33 & R34 and audio probing around I found that Q2's Emitter pin was not in the socket. So I now have clean signal blended in as it should. I felt bad since I said this was verified to the best of my knowledge and I knew I was getting clean blend when I verified it but lost it when I boxed it up. Reason for that is I changed out the transistors from 2N2222A to the 2N2484 transistors when I boxed it.

I reflowed everything, accidentally broke a track on a pot and jumpered it, and then knifed all the gaps, scraped all the resin. It is now working almost correctly. I now have volume, tone and overdrive control, but I still cant get a truly clean tone. It is a little gainy no matter how I set it or adjust the trims. Maybe its just like that? I need to take new voltages to compare to these, too.
