Ooph and I was hoping you hadn’t hidden the ground ratlines. That’s a doozie

Good catch. Schematic in post #72 corrected.

I really need to get this one breadboarded, but I was looking at the schematic and comparing it to the vanilla Phase 90, and noticed something.
Tracing from the audio signal in through to IC1A - it's going into pin 2 (-) on this schematic, but on the standard Phase 90 it goes into pin 3 (+)... granted, going through all of the ICs both the "A" and "B" pin attachments seem to be similarly reversed. Was this intentional?

Schematics in posts #72 and #83 have errors.
I just now corrected post #72. IC2A & IC3A were drawn upside down in the previous version.

Not any more. Thanks again for pointing it out.

@Chuck D. Bones Just coming by to say how impressive it is that you know how to do this stuff. I feel like a wizard knowing how to read basic boost schematics and breadboard them, but this is the kind of stuff I really want to learn and be doing. Thanks for all the help so far! I would have quit this hobby if you and @BuddytheReow and @Feral Feline hadn't taken the time to answer my questions.
