Hey Yall!
Been busy at my normal job so my "night job" of building pedals and posting them has taken a hit.
Thanks to all the helpful comments here and just a steady diet of building and debugging I will say that I've gotten so much better at diagnosing problems. In this case, I have my first attempt at a Phase II and while it seemed to come on and the LED/LDR combos in relation to the pots seem to all work (rate and depth reflected), the signal is a distorted mess.
I _think_ I've tracked it down to the left side of IC1. The right side (pins, 5,6,7) all sound normal, and clear. The left side (1,2,3) sounds like an overdriven, distorted mess. From my read of the schematic, I have a feeling it's something with biasing but this is where I get lost. Should I be looking at R5?
Any thoughts are appreciated!
