OK. I've spent hours and hours shielding this thing, double checking continuity everywhere, ensuring solid grounding....... Then decided the pick-ups needed to go, and spent $300 on a set of Nordstrand split coils - supposedly hum cancelling. Just dropped them in and...... THE B@$%^RD STILL HUMS (buzzes)!!!!!! WTH!!!!!!? Am I being extremely dumb or naive in thinking I can get a hum-free bass? Note: this is the kind of hum which is basically silent when facing one direction, but gets progressively louder turning 90 degrees. I'd even say with the Nordstrands in, the buzz/hum is broader spectrum (more trebles). I'm at a complete loss. HELP.
