Hi there. I'm a new member (today) so please don't flame me if I'm posting this is the wrong forum or haven't searched properly (I've tried!). I own a number of lovely basses, but my main gigging bass is a gorgeous Wal Custom 5 (http://en.wikipedia.org/wiki/File:Wal5stringkauri.jpg) Yesterday in rehearsal it started to distort quite badly when I plucked aggressively. Assuming a failing battery I came home with a brand new battery today and fitted it. To my horror, the output level has dropped to almost non existent. It's there, but only just. Really. I checked it on both pickups and with the active/passive push/pull switch in and out. No difference. Just the very faintest output level. I tried it in a different amp. I tried different basses in the original amp... All points to a problem inside my Custom 5. Can anyone suggest any reason why an active bass should suddenly have such a radical drop in output? Preceded by some nasty distortion. I'm thinking that some electronic component must have fried. One of those funny capacitor or resistor things that I simply do not understand!! I'd love to hear some thoughts from some of you more technologically literate guys. Thanks very much for any advice.
