First post in this section, pretty sure this is the place for it.
Basically, I'm having an issue with the preamp in my Fanndec 6 string, but I'm at a serious loss as to what it could be! Its a 9v 3 band EQ (bass, mid, treble) with a master volume and pickup blend. It works fine, except the bass control, which seems to add a layer of distortion at its furthest + level. As its one sealed unit (unknown make) I can't really do much with it, other than change it for a new preamp and hope that sorts it. Before I do take that plunge though, would there be any suggestions as to what has caused this to occur? I'm quite handy with a soldering iron, so can check wiring etc quite easily, I just don't know where to start?!
Also, I'm experiencing some volume level differences across the strings, notably on the G and C# being significantly louder than the lower strings. I've tried changing the pickup height and saddles to try and alleviate this, but no success so far. Any thoughts on this also?
Can try and upload some pics of the preamp cavity if anyone thinks this would help diagnosis?
Cheers,
Mark
