Re: Fixing scratches on pickups
Seems to me the correct answer is Bobbin Toppers. Protect against scratches, and cover any existing ones. Though metal pickup covers are nice, they can have an impact on sound (slightly boxier, sometimes outright dull, depending on quality).
Thinning the top of the pickup doesn't strike me as a wise course, especially if you just chew the top up again and have to repeat... Nor does using epoxy fillers or something (plus getting one that is properly tint matched could be an issue. Better to just hide & prevent it worsening.
