The "NY" refers to "New Yorker"; in the '60s, before us vintage snobs got so deeply involved in parsing guitar history into millions of disgusting details, "New Yorker" was a generic term for the old 12-fret Martins that were first made in New York and later in Nazareth, PA. The 60's was the age of heavily braced monster-sized steel string guitars, while the much earlier New York style guitars, which were originally made for gut strings, were extremely lightly built and super resonant. The sixties being the height of the folk music renaissance, Martin decided to add a couple models to appeal to the folkies, almost inadvertantly creating the two best models of the decade. This one is single 0 size with mahogany back and sides and spruce top, 12 frets to-the-body, slot-head, single tone bar and has a remarkable sound that has captivated players such as San Francisco blues guitarist Roy Rogers. Our available 0-16 NY is a prime example, is excellent condition and setup, all original, with recent high-end 16:1 Waverly tuners and the originals in the case.
