This Custom Shop Authentic replication of a 1937 D-18 stays true to the original with hide glue construction and historically accurate detailing. It features genuine mahogany back and sides paired with an Adirondack spruce top, along with an Authentic circa 1937 bracing pattern. Stage 1 aging lacks the heavy wear and tear of a well-worn instrument and instead features the light checking inspired by those rare guitars that were simply kept in a case and tucked away for decades. It bears the marks of time but not the heavy wear common on newly aged guitars.
