Re: can you cover uncovered pickups?
I've done this..FORGET taking your current covers off, trying to unsolder a cover is a major b*tch, all the potting will run out....soldering a new cover ON is about as hard, you have to know what you are doing & have a hot bloody gun. Or, again, you'll just melt everything.
I tried adding a duncan cover & running with it unsolderd but even with the trick JumpMarine (airborne deliver guy, eh?) mentions, I got microphonics under heavy gain/volume.
Best to buy 'em with covers unless you are a soldering expert (I've built 3 amps & a handful of pedals & 3 guitars & I have trouble with pup covers)
