And it was very nice! The neck felt a little odd at first, but I'm sure you'd get used to it after a while. And it was reasonably chunky, too.
It was light, sounded good, and played extremely well. I think it had the jack-locks (no idea what the proper term is), that stop the lead from being pulled out of the jack which is cool. Overall, it was on a par with the PRSi in the same price bracket (about £1500/1600 if I remember correctly).
So basically- hats off to Gibson, and if you come across one it's worth giving it a try :)
P.S My personal favourite though, was a wine red Custom- I NEED it! 'Tis £2000 though :(
