IMO, neither of those pups have a "classic" sound, ceramic mags, lots of wire on the 500T. If you play metal, those may be the pickups for you. The 500T is a very strong pickup, almost to the point of blurring your sound.
Very sensitive. Very loud. If you use alot of gain on your amp, you might not like them, as you won't have alot of definition.
I had a 496r, replaced the ceramic mag with an A5, and I use it as my bridge pup now, very happy with it.
If you are truly looking for the Jimmy Page tone, those aren't the pups for you.
