iv been trying to diagnose and repair a noise issue with my bass for a few days now. Iv searched but cannot find answers to this specific issue. I have a used 5 string traben. It has 2 rock field humbuckers that are wired to a 3 way pickup selector, one volume knob for both, and 3 tone knobs. When my right hand gets near the strings an electrical buzz starts that gets louder as I get closer. When my fingers touch one of the tone knobs or volume knob the sound stops. When I touch one of the strings, a crackle or "fzt" sound is made. Touching the strings does not make the buzz stop. Touching any metal part of the pickup switch causes a much louder crackle than touching anywhere else and also doesn't stop the buzz. The noise is quite enough at low volume to not be irritating but at high volume it's much more noticeable. Iv checked everything Iv read to check, and my wiring seemed good. I shielded the pickup cavity with copper tape weeks ago, but I haven't shielded the electronics cavity in the back. Could it just be static from me? Iv gotten ready to remove the electronics and shield the rear cavity but is this going to do anything to the noise? I'm not experienced at all with guitar wiring but I would like to fix it myself if I can.
