Sound Pure's Take
Condition: Used, Excellent
SP Luthier Notes: This guitar has a fossilized mamouth ivory bridge and end pins. A few frets were leveled, crowned, and polished. A full setup was complete. No further work was needed
The Martin OM-18 Authentic 1933 is a breathtaking recreation of a golden-era classic, built to deliver vintage tone with remarkable depth and immediacy. Its Adirondack spruce top with VTS and hide-glue construction produces a dry, open response with stunning clarity and dynamic range, perfectly balanced by genuine mahogany back and sides. The Authentic 1933 neck carve and ebony fingerboard feel substantial yet inviting, encouraging expressive, confident playing. Finished in a rich 1932 shaded vintage gloss with period-correct details throughout, this OM is more than a guitar—it’s an heirloom-level investment designed to open up, mature, and inspire for generations.
From Martin and Co.
The OM-18 Authentic 1933 features Adirondack Spruce with VTS top, Genuine Mahogany sides, and Genuine Mahogany back.
