Ah, Bob's got a point.
The Slash is brighter to me, too. I don't think it is brighter than the PG, though, but I never had them in the same guitar. Is there a reason you want an A2 magnet?
Saturday Night Special neck or Set, you'll be happy. Bridge is a little "more" than vintage, but in a good way, and the neck pickup is clear, has mids, has bass but not too much, you'll find yourself using the middle position on your Les Paul more than you ever thought you would.
