An artful combination of premium materials and skilled luthiery.

You've seen The Six Million Dollar Man; now meet Martin's 5K Uke. This once-in-a-lifetime ukulele features the very best in woods and materials in addition to Martin's renowned luthier skills and quality craftsmanship. The soprano (standard) body is made entirely of solid flamed koa and has a traditional mahogany block dovetail neck joint. O-style bracing gives it the unmistakable sound of a historic Martin uke. The Style 41 abalone body inlay work lends it a classy visual appeal, as does the ebony fingerboard with grained ivoroid binding and abalone flower pot headstock inlay. It also comes with the traditional bone nut, long bone saddle set in solid koa bridge, and traditional-style gold Gotoh tuners. Appointments include a flamed koa headstock cap, b/w Boltaron endpiece inlay, grained ivoroid heelcap, polished gloss finish, and 505 Geib-style case. Comes with Martin M-600 Clear Nylon strings.
