I don't have a dream guitar, as I haven't tried enough to make an informed decision on that. My dream guitar is a guitar that sounds better than any other, is comfortable to play, and after that looks good. Price doesn't matter, I would pay any money for a dream guitar like that. When I find this guitar I'll be sure to let you know.
Although naturally a Gibson Les Paul is high on the list. ;)
You go outside and practice screaming. We'll play music while you're gone.
