Warwick Streamer problem

[Axel F]

I've had a Streamer Stage 1 for a couple of years now, was bought second hand but practically unused from the looks of it. It's been fantastic but about 2 months ago started making scratching noises occasionally when plugged in, lasting about 2/3 seconds. I assumed it was a dirty jack socket but switch cleaner didn't work.

It was getting more and more frequent so I switched out the jack socket. Got it home and it's still having the same problem, albeit less frequently. I rang the luthier who'd replaced the jack who said he thought it might be a problem with the electronics? Anyone ever encountered something similar? Problem continues whether its in active or passive mode (push/pull volume pot).

If it is a problem with the preamp, is it worth me just replacing it with the same stock preamp or is there a worthwhile upgrade? I know a lot of Warwick users swap out the stock preamp and MEC pups.

FWIW:

See FAQ Dimento's Trouble Shooting Guide.

First thing to do is isolate the problem to the bass if you haven't already done so.

You can pretty much rule the jack out. Could be a bad connection or pot gone bad. You can't necessarily rule out the preamp cause depending on how the passive circuit is wired the pre could still be in the circuity and affecting output. Your luthier may be able to answer that. If the pre is isolated from the circuit in passive mode, then it's probably not the pre but in something in the passive circuit.
