A truly special Martin from the golden era. A shade top Martin of any variety is noteworthy, but a shade top from the early 30s- on one of Martins most important ( and rare models) makes this a crown jewel. Many professional musicians feel the OM-18 is the best incarnation of a Martin guitar ever produced. Indeed the OM-18, produced only from 1929-1933, is a different beast than any other configuration. Long scale, Adirondack top, forward shifted bracing. Loud, airy, with a ton of sustain. Excellent condition.
