This Martin D-28 Custom Shop creation redefines the legendary Dreadnought by exchanging traditional rosewood for Highly Flamed Koa on the top, back, and sides. The result is a visually arresting masterpiece that offers a brighter, more articulate punch while retaining the powerful bass response and projection D-28 players expect. Under the hood, forward-shifted Golden Era scalloped bracing allows the Koa to resonate freely, delivering a complex, mature tone right out of the case. Distinctive details like the authentic diamond volute, Grover vintage-style tuners, and a polished headplate elevate its classic aesthetic. This is a rare opportunity to own a "one-of-one" instrument that seamlessly blends Martin’s historic workhorse reliability with the exotic beauty of fine Hawaiian tone woods.

CASE/GIG BAG: Hardshell Case Included.
