This is a Ko'olau Tenor CS model ukulele. This is a new model for Ko'olau introduced this year at the NAMM show. It features a spruce top with abalone rosette, very curly Hawaiian Koa back and sides, with an ebony bridge, fingerboard, and faceplate, M.O.P. logo, and Gotoh tuners. This contemporary series has a new radiused fingerboard, and redesigned neck/headstock. Ko'olau consistently produces some of the finest instruments to come out of Hawaii including ukuleles, acoustic guitars, and lapsteel guitars. Mahalo.
