I have some kick ass old Teisco Goldfoil pickups that I want to wire into my current guitar project, the only problem is they're really noisy. Lots of extra squeals and feedback. I am thinking about wax potting them to cut down on any excess noise. I'm hoping between that and lots of copper shielding it should take care of the problem. Does anyone have any info or tips about how to go about wax potting?
