Re: baritone guitars
Very late to this poll...
Baritones are wicked cool. I use one for layering different parts on songs. They can really fill out a mix well, and allow for unusual textures and voicings. I've set up my Schecter baritone with pickups that make it sound like 600 pound tele - definitely not Nu-Metal!
The clean tones are to die for. And big power chords will kill you, but in a good way. And I'm talking about low-gain, not super saturated mush!
Fun for songwriting, too. The longer neck and heavy strings discourage whatever stuff you might usually play. It inspires new ideas!
