Well, I've got the first generation G45 Studio and mine is excellent. Zero problems. Put some Elixir 12 gage Nanowebs on it a few months back and it has been a great guitar the whole time I've owned it. I've only ever gotten to play one of the new G45s, and I was underwhelmed by the feeling and sound of it. I'm not exactly sure what the big difference is, other than the player port, but my first generation G45 just feels and plays more comfortably.
