I know virtually nothing about "guts". I hear talk thrown around about op-amps and discrete components and such and am usually able to follow the flow of an argument/opinion/etc about different pedals. This talk about "goop" intrigues me, though. All I know about goop is that its use is controversial in the TGP community (controversy is always fun!) and it's used to prevent reverse-engineering. Sooooo, what's the low-down?
