"1937 was an excellent year for guitars with a perfect storm of craftsmanship, innovation, and materials. This Authentic Series replication of a 1937 D-18 stays true to the original with hide glue construction and historically accurate detailing. This guitar features genuine mahogany back and sides and an Adirondack spruce top, and it includes an Authentic circa 1937 bracing pattern. It includes period-correct "18" Authentic-style appointments and an Authentic neck barrel and heel, and new this year, a more accurate body profile based on dreadnought shapes from the early Golden Era of Martin’s history."This beautiful 2008 Shadetop D-18 Authentic 1937 is in excellent condition only showing light signs of wear. It plays beautifully with low action and delivers a rich, woody, balanced tone.OHSC included.
