I've got an RG7CT (which is pretty much what you're looking at here without the vine inlays)
I dont' tune it down to A I keep it in standard b , but I recently dropped in a Rebel yell in the bridge and I absolutely love it.
It's not a uber modern sounding pickup (it is not scooped or compressed at all) but my low B stays very tight and articulate and the pickup just sings for playing lead (which is what's important to me)
Nick over at the Axe-Palce described it to me as a "tighter sounding Nailbomb" and that description is
pretty dead on. I don't know what style you play , I play more of a prog/shred type of metal.
No Death or black metal, not very "Djent.y" either .
I have an Aftermath going into my Bernie Rico 7 this weekend so I'll be able to comment on that next week.
I'still a little torn as to whether I'll will like the Aftermath better than a Holydiver in the Rico but I guess I'll find out soon enough. I haven't heard anyone not liking the Aftermath is a 7 yet so I'm hopeful.
BTW this is going thru a Mesa Mark IV-.recto 2X12 cab.
