The Martin O'ahu HG-28K2 brings an all-koa voice to the Martin O'ahu family, expanding the collection's distinctive HG body with a look and sound rooted in Hawaiian music history. Best described as a smaller sloped-shoulder Dreadnought with the depth of a 000, it delivers bold, balanced sound without the full-size body feel. A solid koa top pairs with solid flamed Hawaiian koa back and sides for strong midrange projection, natural compression, and rich overtones, while the short 24.9-inch scale adds a smooth, comfortable feel. Finished in gloss to highlight the natural figuring of the wood, the HG-28K2 offers a warm, expressive all-koa voice within the growing Martin O'ahu lineup.

The Martin O'ahu TKE Uke Burst introduces the first ukulele voice to the Martin O'ahu family, bringing an instrument central to Hawaiian music into a collection created to celebrate that legacy. Its tenor body—the largest ukulele size Martin makes—pairs a solid spruce burst top with solid koa back and sides for added volume, projection, and clear, responsive tone. It comes strung with Martin O'ahu™ Low G Ukulele Strings, whose silver-wound Low G adds depth and resonance while offering a more familiar transition for guitar players exploring ukulele. Mi-Si Simple Jack electronics make it ready for amplified performance, with a battery-free preamp that charges in 60 seconds for up to 16 hours of playing time. A gloss body, satin neck, antique white binding, nickel open-gear tuners, and included softshell case complete this stage-ready tenor uke.

Hawaiian musician Major Kealakai and his Martin guitar helped shape the course of music history. Kealakai was a guitarist and conductor of the Royal Hawaiian Band, and in 1916, Martin made him a unique custom guitar that was wider, deeper, and longer than a 000 to provide more volume and help fill concert halls. That one-off guitar was the precursor to the iconic Dreadnought. Now, Martin is honoring that historic milestone with this new take on his 12-fret guitar.
