I dramatically upgraded my rig a few months ago. Suddenly, I'm getting wierd noises at random. The noise sounds EXACTLY like wind blowing across an open microphone. Not crackling. Not popping. It's that blustery sound. If I yank the cord out of the bass it vanishes. I seem (SEEM) to be able to induce it by rotating the pots on the bass, but this is not reliable. And I get the noise from time to time even if I don't touch anything at all. I've ruled out cable noise by swapping cables. I suspect dirty pots in the tone section of the bass, but a dirty pot doesn't make any noise if you don't touch it, right? Here's the rig: -1997 Carvin LB75A -1991 SWR Grand Prix preamp, probably with the original tube -Unknown vintage Stewart 1.2 -New Avatar B212 Could this possibly be a preamp tube crapping out? Or is it more likely a dirty tone pot on my bass? I suspect a dirty pot on the bass, but it doesn't have the staticy, crackly sound that you'd expect from a dirty pot. HELP! HELP!
