Okay all you pros, luthiers, and players alike. Many threads have been started about wooden pickup covers, but I've not heard of anyone mentioning some important issues. I need some help resolving some issues. I've got a custom made Linc Luthier bass with Villex pickups. The Villex pickups are wound into custom made Macassar Ebony shells made by Linc. They look great, but there is a problem with buzzing in the pickups.... I'm already on my second set. Villex pickups are known to be dead quiet, so that's not the culprit. BTW, Villex's pickups sound fantastic. As for my bass, the first set was lacking shielding, so it buzzed terribly. The second set, Villex lined the shells/covers Linc made with copper foil. It's much quieter, but the buzz the first set had comes and goes sporatically. Villex thinks it's a problem with conductance cause by the wooden pickups and moisture in the air. He thinks that this newer set is shielded well and that the problem is not from that.... He thinks that new pickup covers should be dipped in some sort plastic material to isolate the pickups....or to have the pickups finished with a plastic-stlye finish (a poly). Mind you, these are bar magnets, not poles like Nordstrands or Aeros, and the poles are under the covers themselves, and there are no plastic covers underneath the wood. Has anyone experienced that problem? Kent Armstrong makes wooden covers, does anyone know how he isolates the wood? I need some help!!!!
