Yes I've seen that SA64-90 of yours before and it inspired me to try and find one in that colour hence my bid on the unknown SA the other day. They are outstanding guitars and should get just as many kudos as the L.P's IMHO. My SA64-70 came with '57 classics already installed so I don't know about the Screamin' pickups much. It has a wide, flat neck and is a joy to play! Rich, full and jangly if needed but on the bridge with crunch it really howls.
I'm not a fan of L.P.s at all really. I sold my EGF850 last year because it just didn't sound like I wanted it to. The PU-2 pickups that command so much attention here just didn't do it for me at all. I know some people love them but to me a humbucker REALLY shines with some AIR to work with.

Love the semis.
