I removed Goop from a Klon with a fried 7660S Charge Pump with a Dremel & Carbide tip.
You know it's Gooped on the Back as well.
I thought that was a Challenge, Good Luck!!!!
So, I'll start the guessing: Looks like it could be a series of gyrators. I thought I heard some pretty sophisticated EQing when I played it. Thought it sounded a bit like a cab sim in there - very polished sound, like you were listening to yourself play on an album.
Kind of a joke gooping circuit boards. One guy with the skill and patience can reverse engineer it and post the schematic on the internet for all to see. Go PedalPCB!
