Every time I stop by the guitar center I used to work I pick up the same Martin. The model is some model they make exclusively for guitar center. Doesn't really matter, it's a dreadnought. Simple varnish finish, rosewood back and sides. The guitar doesn't boom like a gibson, but the overtones are to die for.
If I was in the money to buy an acoustic I'd have a tough time not picking up a Taylor 110. Amazingly bright and resonant for half the price. Something I'd feel more comfortable street gigging with.
