The all-new Custom Shop 000-18 1937 gives players the sonic qualities of the Authentic Series paired with the everyday value of a trusty workhorse guitar. Regarded as the cornerstone of performance and sound, Martin’s highly prized 1937 models set the bar for generations of instruments that followed. This guitar features a clear vintage gloss Adirondack spruce top, genuine mahogany back and sides, scalloped bracing, hide glue and cloth strip construction, and an adjustable truss rod, capturing the look, feel, and sound of some of the finest guitars ever made.
