Martin Guitar Debuts First O'ahu Ukulele and All-Koa Guitar
Nazareth, Pa. – October 06, 2026 -- C. F. Martin & Co. is adding two new instruments and a set of ukulele strings to its Martin O'ahu collection, a line inspired by the Hawaiian music craze of the 1920s and early '30s.
An all-koa guitar joins the lineup at $4,199.99
The Martin O'ahu HG-28K2 expands on the existing HG-28's sloped-shoulder design, pairing a solid koa top with solid flamed Hawaiian koa back and sides. The body shape sits between a smaller Dreadnought and a 000, with a short 24.9-inch scale meant for easier playability. The gloss finish highlights the wood's natural figuring, and Martin says the all-koa build delivers strong midrange projection and rich overtones.
