While I've grounded pole pieces successfully on other pickups before with no problem, for whatever reason the conductive adhesive on the roll of StewMac tape I currently have won't work with either my Lollar J's or P pole pieces. I've cleaned the surface of the magnets with alcohol & naptha and I've burnished the living heck out of the tape but when I check for continuity with my multi-meter it's a no go. Occasionally I can get a one or two pole pieces to ground d but never all of them. The StewMac tape does have continuity when I tape it to itself shielding control cavities. Is there a better conductive adhesive shielding than the StewMac? Do I have a bad roll or does anyone have any other tips? I can't recall where I got the shielding I used in the past but had no issues making that work.
