I skipped ahead a few videos, to Joe’s waveshaping tutorial. It seems like the first video uses a sine (set to 220) to modulate the phase of a sine wave with ~0 frequency. I don’t get this, wouldn’t a wave with 0 frequency have no phase? What am I not getting?
Is it theoretically possible for someone, not myself for sure, to recreate a distortion pedal in the er-103, by looking at the schematics?
