pt2399 add-on boards

[fuzzmonger]

Hi there,
Wondering if any of you had any schematics, layouts or links for pt2339 delay add-ons / daughterboards for weird shit like modulation, envelope detection (like that Mid Fi pedal I can't remember the name of right now) or maybe even a sequencer for delay times to get glitch/stutter sounds. (preferably no taptation stuff. I'm trying to keep it cheap)

I tried to translate the Echo Base modulation section into a perfboard / single-side PCB but I just couldn't come up with something workable (because I suck so bad at turning schematics into neat layouts). If anyone has one knocking about that they'd like to share the please, do
