About the Custom K-1 Major Kealakai

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.

About the Martin O'ahu HG-28

Crafted with flamed Hawaiian koa back and sides and a solid spruce top, it produces a beautifully balanced sound. The satin-finished short-scale neck offers smooth playability, while the bold herringbone trim and antique white binding add some vintage charm, reminiscent of Martin’s early Hawaiian-style guitars.
