pickup cover question

[jclogston]

Hi all -
Pardon me if this is a stupid question, but i had a question on pickup covers. I'm looking to get the duncan distortion and full shred for my guitar but prefer to have the pickups covered then have the coils showing. Would these work?

And can i just place them over the pickups or do i need to do more work?
Thanks
