i actually already had a gibson sg special when i got the SE. i think the SE was a lot more smooth. the SG just had rough fret edges, and the pickups just didn't sound as clear as i would have liked. it could have just been a bad guitar, but the SE felt a lot more well put together. gibson's a little notorious for bad quality control on some of their lower models. i don't think it's as bad as some people claim it to be, but it's definitely got a little bit of truth to it.
anyway, the SE's are supposed to be pretty heavily checked over, and from what i could tell that seemed to be true. plus i bought mine from www.sweetwiter.com. it's kind of like a smaller and more personable musiciansfriend.com or something. anyway they set up their guitars before they send them out, so it felt great by the time i got it. could have been part of the reason my SG never felt as good. i had the SG set up professionally a few times, but it never came back feeling much different than when i sent it in.
hope that helps haha oh, and no matter what the bridge is on PRS (vintage style trem or stoptail) you should be able to get the action where you want it. mine had a stoptail (hate vintage trems) and the action was just about as low as it could be without buzzing. felt great.
the reason i got rid of the SE, in case you were wondering, was that i had the SE Soapbar II and the P90 pickups just hummed too much for me. wish i hadn't sold it now, but what can you do, right? :dontknow:
EDIT: the website i bought mine was www. sweet wAter .com but for some reason every time i hit "post" or "save" it changes it to sweet witer .com ...very strange.
