OK, read your post, alot of covered factory p/u's have glue or solder on them, sometimes a hot soldering iron and a careful steady hand will get the cover loose, be careful if you try it, but if you are going to replace it with a humbucker why bother? I was glad to see that you just got curious and opened it up for a look, too many people are afraid that taking out a few screws will do permanent damage, gotta learn some way!, if a person has enough sense to use a screwdriver, an allen wrench and a soldering iron they can learn to do just about anything to a guitar, just remember if you screw something up, don't blame me, but if you have any questions feel free to ask........
