Give jimi Hedrix any guitar and he'll still be jimi hendrix. With that said I still feel it's important to get a guitar that suits your play style and music you make. I play with a Taylor 314CE I love the cutaway, and teh bright tones suit the genre of music I like mainly soft rock, folk, indie, etc.
If you preffer bands more along the lines of Nickelback, Nirvana, Rock bands with more of an edge, a standard dreadnaught is the way to go.
Taylor is brighter, cleaner, crisper Martin is Warm, Rich, mellow
