This special edition D-18 acoustic guitar is Martin's loving recreation of the original 1937 guitar, now a highly sought-after collector's item. Crafted with mahogany back and sides, a solid Adirondack top with the X-brace and scalloped braces of the period, hide glue, vintage toner on top, ebony bridge with long saddle (2-5/16 string spacing), and a tortoise pickguard. The neck is also formed exactly as the original and reinforced with a traditional non-adjustable T-bar. Ebony fretboard (1-3/4" nut, 25. 4" scale), small abalone position dots, fossil ivory nut and saddle, ebony bridge pins, 30's style hardshell case. The features and details add up to a true masterpiece of the luthier's art, with all the storied sound quality that graced the original pre-war guitar."
