I want to upgrade the pickups in my Epiphone Wildkat. They are really dark and muddy sounding. I know about the wiring deal and plan on rewiring it. It is mainly the micro-phonic squeal I cannot deal with so I want something with plastic covers. I know people will say just replace the metal cover with plastic, but this is easier said than done considering the neck has wacky pole spacing and the are welded to the pickup. Any suggestions preferable from someone has done it and it worked out to be an improvement. So far I have heard good things about GFS that they fit good-any truth to this?
