Help? I've followed all of the posts to a "t" - I think Copper foiled myself and my bass to deat - you should see my fingers - that crap is SHARP! lol Set up - Audere JZ3, Dimarzio Ultra Jazz. Pickup cavities are shielded, cavity is shielded, bridge etc. What could I be doing wrong? does wire gauge (the one coming from the bridge) make much of a difference?
