Matt, I played an artist pkg version of the production 594 yesterday at CR Guitars.
All I can say is: wow. And -- as I think you know -- I speak as the [now former] owner of a vintage Les Paul with PAFs and the whole package. (it was a boogered-up '52 that ended up being turned into a '59 by arguably the best guy in the business) I thought the 594 came closer, overall, to the vintage Gibson in terms of feel, look, and sound, than any of PRS' previous efforts in that direction. Including, notably, the Hammer of the Gods single-cut. Caveat: I haven't played any of the "Miss February" run.
It was also way better, in all respects, than any of the bazillion R9s I've played & owned.
Bottom line is, if I wanted to have a guitar with that feel, look, and sound, I'd have bought that 594 then and there.
