Tough one.
This is schematics for some Jazz Chorus, I don't know which

So here's an interesting google result for you:
http://www.harmony-central.com/Guitar/Data/Roland/JC_120-01.html
In the middle of that there's a review for Rusty Crites (use text search), who apparently was able to find some schematics for jc120. The guy left his email; given that review is 4 years old, your chances of getting through to him are slim, but email is free so maybe it's worth trying if the pdf above is not what you are looking for.

Some more:

thanks guys. i think i'm getting close to having it up and running. this old one has got a really cool, nasty sounding fuzz. might be a fun tone to jam with!
