check this vid is matt using a semi hollow? hes the vocals.
Yes, he's using a Gretch.
Ah, so are those like semi hollows for indie and punkish stuff?
^No... There are no guitars that are specifically made for playing punk and indie... Gretsch is one of the most reverred manufacturers of hollowbodies, and they're used in all genres. As are most other guitar types.
Gretsch are "made" for rockabilly and classic rock if any style. Even if they would do punk and indie, I find them to be too low output and too twangy. I would recommend another guiatr for those styles.
