Martin 0-15 (1951)

This 1951 Martin 0-15 is a great entryway into the world of vintage flattop guitars. Popularized in recent years by Kenneth Pattengale of The Milk Carton Kids, the 0-15 was Martin's smallest student model guitar for most of the 1950's and early 1960's. Its all-Mahogany construction is only significantly different from a style-17 in its lack of body binding (though it effectively took the place of an 0-17 after the move away from scalloped bracing in 1944). These are great fingerpicking guitars, with a warm, dry sound; though as Mr. Pattengale has so aptly demonstrated, they yield an archtop-esque snarl when played with a flatpick in an acoustic duo.
