    OK, before I get pissed and sell a set of Dimarzio P's, any idea on why my bass now hums like I have a bad ground? I have checked and rechecked all of my connections. It was working perfectly, then a few weeks ago started humming. This is my backup bass, but I still want it working properly. Any ideas?

    Assuming you've isolated the problem to the bass itself, check all my grounds with a meter for continuity - pot to pot, etc. Be sure to check from bridge to jack. Nothing there I'd probably isolate the pups from the harness and wire them directly to the jack (or to a seperate jack with pigtails). Just rig it temporarily and wirenut the wires together and include the bridge ground. If no hum then you know it's not in the pups. If you get hum then it may be the pups or it may be a bad connection but at least you can easily recheck your connections by pulling on all the wires and/or reconnecting your wirenuts.

    May or may not resolve your problem but it's a simple and it's a start.
