The T1K Uke showcases Martin’s long-standing tradition of crafting exceptional tenor ukuleles with premium tonewoods and timeless style. Built with a solid Hawaiian koa top, back, and sides, it delivers a warm, lively tone with beautiful sustain and clarity. Koa is native to Hawaii and has been a favorite of island players for generations—not just for its rich sound, but for its naturally striking grain. The hand-rubbed finish brings out the wood’s natural beauty, while an applied dovetail neck joint and nickel open-gear tuners ensure solid construction and smooth performance. With its full-bodied voice, elegant design, and legendary Martin craftsmanship, the T1K is a tenor uke made to be played for a lifetime.
