Hawaiian musician Major Kealakai, and his custom 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 a new take on his custom 12-fret guitar with a refreshed bridge design to better complement the traditional specifications, as if the company continued to produce it well past 1916. The Custom K-1 Major Kealakai features vintage gloss sinker mahagony back and sides, an Adirondack spruce VINTAGE TONE SYSTEM® (VTS) top, hide glue construction, authentic 1931 X bracing, and a modern, embellished ebony pyramid belly bridge. It blends tradition and innovation, paying tribute to the rich heritage of Martin.
