C.F. Martin & Co T1K Koa

An "All Solid Koa" Model Designed to Go Further

With its luthiery focused on solid Hawaiian koa, the T1K Koa positions itself as a ukulele with a distinctive personality, designed to offer more nuance and dynamics than a laminated wood model. Its design emphasizes body resonance and the stability of key components (Tusq nuts, Grover tuners), making it an instrument ready to accompany years of playing, both at home and on stage.

For Which Player and Styles?

Thanks to its 15" / 381 mm scale length and 20 frets, this ukulele is particularly aimed at intermediate to advanced players who want more ease for enriched chords, fingerstyle, and melodies high up the neck. It is also suitable for a demanding beginner seeking an inspiring instrument with immediate response and real expressive potential. Ideal for pop, soft jazz, folk, vocal accompaniment, and solo arrangements.

Sound Characteristics

The solid koa provides a very musical balance: precise attack, present mids, and controlled brightness, with warmth that develops as the wood "opens up" over time. The solid Sitka spruce bracing promotes projection and clarity while maintaining good sustain. The 15" / 381 mm tenor scale enhances note sustain and definition, particularly useful for melodic playing. The morado (or rosewood, depending on configuration) fingerboard and bridge contribute to a firm playing feel and balanced response.

Recommended Compatible Accessories

To meet the specifications, Martin Ukulele 620 strings are a coherent choice. A clip-on chromatic tuner is also suitable for quick and precise tuning. Since the instrument is solid wood, an acoustic instrument humidifier (to be used during dry periods) and a microfiber cloth will help preserve stability and the satin finish.
