Thanks for the advice and schematics! yeah, this is so far over my head it's not even funny. I've got a buddy that was a radioman for the marines and he's an electrician now so maybe he can help me out with this haha.

I really appreciate it! I'll post an audio file if i can get it working again!

I bought a crate flexwave 120 with a 4x12 half stack off craigslist for $250. I tested it out before I bought it and it sounded good, and the guy I bought it from was a pretty well known re-seller of used equipment so I wasn't too concerned. I had it for about 3 days and the effects processor started kicking on randomly and now the overdrive channel won't work at all. When i push in on the knobs it will pop and kick on but if I let go it kicks back off again, and the volume control is awful. The high gain channel still works, but it's quiet. The clean channel works fine but the flanger will turn on by itself at random and at full blast. Drives me nuts.

I'm really not wanting to buy another amp because I love the way it sounds (when it works) so i'd really like to fix it. All I really want is the clean, OD, and high gain channel. If the onboard effects never work that'd be fine with me i don't really care for them anyways. Could someone give me some guidance or advice? I'm kind of electronically retarded so schematics would probably be over my head but I'm going to try everything i can before i give up on this amp.
