Re: Who makes a nice Firebird Style guitar?
The Dean Trans Am is really, really nice. Due to design (specifically, location of strap button), it balances better than the traditional Gibson/Epi body. Stock Dean pickups are usually quite usable, and the guitars just feel solid.
Diamond (formerly) DBZ has the Hailfire, which also feels solid but is more traditionally balanced like the Gibson/Epi body (i.e., 1st fret feels a mile away). Diamond also has really interesting finishes, if that's your thing.
