circuit board question

I have just put together a Kliche Boost SKU: PCB142. I suspect I may have dinged a PCB trace because I have no continuity between the junction of R8/C6/100KPot to pin 5 on IC1.2. The PCB is loaded so tracking down the trace is proving to be extremely difficult. Is there any way to get an overview of how this trace gets from the junction of R8/C6/100KPot to pin 5? It's not that big of a deal to just order another PCB if this can't be made available. BTW, I have 2 other successful builds. Really gorgeous work on the layouts!

Thanks!

The schematic is super helpful in this case. This is how you learn to read them.

OK...So I put it aside for awhile and I just took some time to troubleshoot. First off, dumb mistake I was mixing up IC1 and IC2 as I was troubleshooting previously. Yes the charge pump was working fine and all IC's were powered as they should be. These PCB's are gorgeous but eyeballing traces is next to impossible. I did mess up some cap values which wouldn't have killed the project. I also found some bad resistor values due to them being the 4 band style and I'm more used to 3-band style. I think the big kicker was that I put in non-polarized 1ufd mylar caps in place of 1ufd polarized electrolytic caps. I always think keeping electrolytics out of line of the audio is the better way to go, but in doing so possibly some DC was intruding where it shouldn't be..? I gotta be honest, to me this appears to be a pretty strange circuit. Didn't really take time to dive into what is going on with switching but it apeears that some of the circuit stays inline so it isn't true bypass. Got it working on the bench. I'll have to slap it into my pedalboard and see what's going on.

Correct, it's a Klone, it's buffered bypass.
