As much as I appreciate it, and the work involved, I am confused by your drawing. Are you subbing a 13700/13600 for the original 3094/1048?
Yes Mark, since I can't find CA3094, I decided to recreate this using LM13700. Also, I confirm that R21 and R37 on my schematic are not necessary - they're present in the "official" schematic, but not on the PCB photos you've shared. But I'm still not sure about C23 (10u), it's not present in original schematic, but I believe I saw it on the PCB. It definitely affects operation.
I must ask Mark or anyone else having an original pedal, to check out R2, R4, R5, R6 value. They seem as 1k to me (if photograph colors are right), not as 10k as shown on original schematic.
