Recently bought a used Warwick Thumb from 1994, it plays amazing but the electronics don't seem to be working properly. For example when I turn the volume knob I get a really loud "white noise" sound when it isn't either maxed or off completely. And the treble pot can't be turned from the 12 a'clock without it making a similar white noise. Anyone know what could be wrong? I have very little experience when it comes to electronics so I am at a complete loss.

Warwick Thumb bass 1994, incredibly noisy MEC preamp?

Just so we're on the same page..."white noise" is a hissing or "whooshing" sound, similar to the sound of wind blowing or water coming from a faucet...
I presume you are still able to hear the bass through the white noise, but it's not clear from your post. I also presume you're plugging into a bass amp and not (for example) a recording console and monitors.
Solid state components like transistors and op-amps can fail in such a way that they generate white noise. If that's the case, in most cases it will be simpler to replace the preamp than try to troubleshoot and repair it, in my opinion.

Oh sorry, realize now I gave very vague info. But it's sort what you describe as a whooshing sound, not really hissing but more just like a weird wind type of sound. And yes I can still hear the bass through it, but anywhere that isn't max it would just sound hideous as it is very loud. And yes I am playing through a real amp, and the amp is working perfectly fine, and the bass doesn't really have any issues when played in passive mode (besides it being way too quiet). So you think it's best to just buy a new pre?
