Martin OM-21: A True Original Acoustic A true Martin original, the Martin OM is considered by many to be the design that ushered in the modern era of acoustic guitars. Martin unveiled the OM in 1930 as their Orchestra Model — a new body design that departed from the 12-fret designs they had offered since their founding in 1840. The Martin OM offered a 14-fret neck and a 000-inspired body that translated to big, projected tone — ideal for the popular dance hall and orchestra-style performances of the time. The Martin OM-21 of today stays true to the OM of the 1930s, featuring a classic Sitka spruce top, rosewood back and sides, and select hardwood neck with ebony fingerboard and modest appointments that keep the price point lower but the sound still at the top. One of the new features of the Martin OM-21 is the Performing Artist neck profile, which features a shallow oval shape with a slightly narrower taper than a typical OM’s neck.Martin OM-21 Acoustic Guitar Features: 000-14 fret acoustic guitar with timeless Martin tone Performing Artist neck taper and satin-finished neck responds beautifully Rich lows, detailed mids, and smooth highs from the rosewood body topped with spruce Expect a lifetime of reliable performance thanks to premium components like the real bone nut.
