Kliche Overdrive - No Input?

[jalcumb]

Hello everyone. I just finished a kliche overdrive, the problem is all it does is hum when it's on. The volume pot makes it hum louder and quieter but no actual guitar signal seems to be getting through.

The last thing I tried before this picture was switching the lugs connecting to the in on the PCB and the negative battery connector. I can't remember if the pedal was even humming before I did that so I don't know if it changed anything with the signal, but now the pedal doesn't turn on from battery power, it requires the wall plug to turn on.

I can remove everything from the enclosure for more pictures if needed but for now I'm hoping that someone with more experience will see the wiring or the symptoms and have an idea of the problem.

I will also take troubleshooting advice anyone has. I have just been doing continuity tests on things that make sense but that's basically my troubleshooting experience.

Thanks for the help

As an audio probe alternative, do you have a synth? Something you can latch with a basic tone? Maybe an oscilloscope? There are some crazy inexpensive items that aren't great for every situation, but I have gotten a TON of mileage out of a pair of these: Fnirsi DSO-TC3, which looks like they have upgraded to TC-4 (on Amazon). I bought two because I accidentally killed the component tester circuit (do not put voltage there!), but they are both signal generators and oscilloscopes, so you can use one to put a signal on your board and the other to track it.With this in hand, you can inject a signal at your input and see if it's visible through the switch and on to the main board.
