I got it!!!! Silly me I misinterpreted the wiring diagram so I had the in/out jacks reversed. I will forever check my continuity between ground and the in/out jacks. Thanks again for the quick feedback and I'm really happy with my build and the quality of the PCB. Sound wise, I was pleasantly surprised how much more bottom end passes through the MK1 vs the MK2 I compared it to. The extra delay time is nice as well. Case closed!
