Hmm, my winered Studio is definitely not flat top
The things I don't like about the LP studios are a flat top, no binding and dot inlays don't look good to me (though some have normal inlays).
That being said I don't think those features are worth the extra $$ for a Gibson LP. So I cheaped out and got an Epiphone when I wanted a Gibson. I would have gone for the Goldtop Studio Raw Power if only it had normal inlays instead of dots.
