Scary problem with my Wal Custom 5. Any help please?

    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.

    I would if I could. Can't even find the link that says: "new thread" in the Wal Club. And yes, I'm registered and logged in.

    Either I'm even more stupid than I thought or the forum is really not very intuitive! ;-)

    I've got the same bass and have had to chase a couple electrical gremlins.
    First I'd make sure the jack is clean and making proper contact. In all my Wals, the jack has been a very dirty culprit. The other dirt culprit is the pickup connector mulit-pins at the boards.
    If it's not that, I'd then carefully and slowly inspect every solder joint with a magnafying glass and light. Make sure the battery leads are still soldered to the board, and every wire still soldered to the output jack (there's about 4 or 5).
    I've had to remove the boards from the bass for servicing. It's not difficult at all, but just work gently.

    Thank you very much for your responses and advice. Much appreciated.

    I will post on the Wal board and also check out the things you recommend, Caca.

    Thanks again.

    So, thanks to Caca De Kick's advice I spent a little time cleaning around the jack input, with a burst of switch cleaner.

    The result?

    She's working perfectly again!

    I would never have though of such and elegantly simple approach.

    That's why i LOVE forums like this one.

    Thanks all and especially Caca.

    Best wishes to all.
