Hey everyone, I found pdfs of most of the Moogerfooger factory schematics and it doesn't seem like we've looked over them here. Anyone able to confirm they're accurate? I'm not skilled enough to do it myself yet (except for the CP-251, that one is way simpler than the rest).

I love how these pedals sound, but insanely expensive these days, especially the amazing MF-104 delay. Hopefully we can figure out how to clone them and find replacement parts, especially for the ones that need BBD chips. I'm hoping the Xvive MN300x reissues will work, but I'm not familiar with all the BBDs here, like the MN3101.

Also, I am missing schems for the other versions of the MF-104 (104Z, 104SD, 104M, 104MSD), imo the 104M schematics are the most important of them but any pdfs or traces would be interesting to compare with the original.

Found them on https://www.synthxl.com/
It's mostly synth schems and manuals but there's some pedal stuff too. I do have the manuals for all the pedals (except the 104) but they can be downloaded from moog's website or synthXL

:lol: behringergehringer will always be funny

Honestly not sure if behringer will actually do it tho. I heard they were asking their facebook followers for schems or gut pics, as if Music Tribe doesn't own an entire fucking town in China they created specifically for R&D.
