Hey all, I recently noticed a problem on my bass. I have a Fender Jazz Bass CIJ, and whenever I just slightly roll off one of the pickups (either the neck or the bridge), it starts making this loud hissing noise. When they're both on max, the hissing stops. I suppose this problem could be related either to the bass, the amp, or the pickups themselves; although it happened to me on two different amps, which made me believe that the bass/pickups are causing the trouble. Any idea why this is happening, or how I can fix it?
