Actually, Randy asked him if it was a gold top J45, which is a Gibson. Phillps corrected him on the model.
Any DMB fan that's seen this guy play can tell he's emulating Dave. I know I did. Only later did I find out he lists Dave Matthews as one of his influences. Obvious. I'm not going to get into the "copycat" discussion as I've seen enough of it on another board.
His GA7 is a nice guitar. Dave plays the same model on several songs.
