This 1919 Martin 00-28K is a rare and beautifully preserved example from the early years of Martin’s use of Hawaiian koa. With its all-koa body, 12-fret slotted headstock, and delicate herringbone trim, it showcases the craftsmanship and tonal elegance that define pre-war Martins. The lightly built body and koa tonewood offer a clear, warm, and articulate voice with strong projection and sweet sustain. A remarkable piece of Martin history, this 00-28K is both a collector's gem and a responsive, inspiring instrument for Hawaiian style playing. For the full repair history, check out the Specs tab. Includes a non-original hardshell case.
