Some of you helped someone try to debug an electrical problem recently, so I thought maybe you could help me. I have an Landing bass - that I don't use - because - there's some electrical problem. It's a passive bass with EMG humbuckers. When I slide my fingers up and down the fretboard, I get a static sound. I also get it when I touch the knobs, which are gold. Can anyone walk me through debugging it? Thanks.
