Hi guys, I'm in the middle of installing Nord DC's into my bass. After installing the first pickup, I found that I'm getting grounding hum (absent when touching strings, metal knobs, etc). I have checked continuity, and get a reading of 0.30 with my multimeter set on Rx10 (pretty much everywhere - shielding to shielding, shielding to jack, etc). Being a beginner at this, I'm guessing that anything but 0 is bad. What's the best way to go about isolating the problem? For some reason, I have a hunch that the problem lies in the shielding.
