I've got this bass, and I really hate the hum. My Alembic doesn't give me this problem. Do I need to shell out $200-$300 bucks for a good shielding job? OR should I dump these Pups for a set of Barts? I gotta be honest though, there is a reason I got this bass. THE SOUND!! and I really don't want to change "the sound" with the Bart concept.
