When I starting learning circuit analysis in college in the 80's I would draw out the pedal schematics via hand-inspection of the board itself and try to figure out wtf they were doing. I didn't have access to part #s until I was in college (you couldn't just google a datasheet for whatever 8-pin DIP was on the board, you had to look through giant catalogs of them from each manufacturer).
Two things immediately jumped out at me ... first, that undergrad circuit analysis does not help understanding circuits designed by wizened experts ... and second, that even the simplest circuits require all kinds of considerations beyond the y=H(x) transfer functions (and that linear systems don't begin to describe what i was seeing). Humbling.
It would be interesting to see how the Chorus schematic from 1985 compares to the Chorus schematic of 2023.
