It's been a minute since I built any wackier PLL circuits, and I drilled this box out months ago for a commission that changed direction, so here's a Tone Virus.
I increased C3 to 33n, and added a 15n cap between R8 and ground for more reliable tracking on the bridge pickup. increased R19 to 10k. 100kA used for all level controls so they could have a bit more usable range before ear splitting
Lag replaces R10 with a 10k pot. Tone connects a cap/ pot from the junction of R19 and C13 to ground (Wave Shape on the Schumann PLL)
Still not a huge fan of the harmonizer-type Schumann-esque PLLs, but this can definitely cop some cool tones. My roommate says I can't use this pedal when she's home, so no demo (for now)
Fairly straightforward build, easy to source parts, gets nasty. Recommend it simply for being a kind easy bake take on the Schumann (which in also not a huge fan of)
