I've got a spare DOD FX-65 chorus that's been sitting on the shelf awhile due to a strange volume issue. The pedal powers on fine, switch works properly (a common failure point on these pedals), and it passes signal both bypassed and effected. The problem is, the signal is rather weak, almost 3dB lower than my signal straight to the amp. This is both effected and bypassed signal. Also, compared to my fully functioning FX-65, the chorus effect is thin and lacking depth. I took the pedal apart and checked the board for any obvious issues. None noted. No components broken or bent, cables seem to be seated firmly in the jacks, etc. I worked some contact cleaner through the jacks and pots too, just to be sure. Unfortunately that didn't seem to work. I couldn't find much about repairing these, so I was wondering if anyone here had some ideas where I might start troubleshooting?
