From what you said, and in addition to the NB recommendation above, I would say the Rebell Yell might be really worth considering.
I would suggested you to listen to Hunter's clips of the RY, especially the one played with his Marshall vintage modern (which is a good pairing, and dunno why, but with your name, I guess it will be a good argument for you :lol:)
Maybe ask him more details on that one-of-a-kind beautiful classic rock pickup. (and of course listen to the S. Stevens demo 8))
Seymour Duncan says the George Lynch "screamin' demon" SH-12 was designed by their custom shop with a more big open sounding than their 59', with more growl.
I only expect the RY to absolutely slays it... :twisted:
I haven't one at home yet, but when I tried it in the past months I was blown away by it's voice : growly, straight talking, focused, cutting with a real agressive temper. I tried it on a SG type body (another story than the charvel) but I didn't find it bassy or fat, at all. It wasn't too bright or harsh either, just biting but in a tasty way...
