Sigma Martin DR-28N Made in USA Rare American-made Sigma Martin USA Includes hard case Made in the USA in the 1980s (1981 or 1982) It appears to be a rare Sigma Martin USA, where Martin imported guitars partially assembled by Terada Gakki in Japan and completed them in Nazareth. Features: Tread Note 14-fret joint Sitka spruce solid top Indian rosewood plywood sides and back Mahogany neck Rosewood fretboard Bone nut and saddle Grover tuners (Martin) Although only the top is solid wood, the supervision of Martin's production and the meticulous work of Terada Gakki combine to produce a wonderful sound reminiscent of the 28 series, though not quite matching the original Martin. It's a vintage item. Strings were replaced in December 2025. (D’Addario Extra Light Gauge Phosphor Bronze) The body has scratches and dirt due to long-term use and storage. Please check the images for scratches and dirt. Sigma Martin USA is no longer manufactured in the United States, making this a rare Made in USA item that is unavailable elsewhere. I hope you enjoy the sound during the relaxed time of the New Year holidays. Year of manufacture: 1980s Body size: Dreadnought
