Martin O'ahu K-42 Hibiscus

The Martin O’ahu® K-42 Hibiscus is one of the most distinctive limited-edition acoustics Martin has released in recent years.

Inspired by the historic Kealakai body shape that helped influence the original Dreadnought design, the K-42 Hibiscus combines a traditional 12-fret K-style body with a modern 14-fret neck—an unprecedented design for Martin. The result is a guitar that delivers exceptional projection, a focused low end, and remarkable responsiveness while maintaining the rich, open voice that has made Martin acoustics legendary.

Limited to just 100 instruments worldwide, it is as collectible as it is inspiring to play.

Visually, the K-42 Hibiscus is stunning. Broad-flamed koa back and sides are paired with a reclaimed spruce top finished in a Dark Toasted Burst, creating a striking blend of vintage character and Hawaiian influence. Elaborate Style 42 appointments, Madagascar rosewood binding, abalone trim, and ornate hibiscus fingerboard inlays elevate the instrument to showcase-level craftsmanship.

Every detail reflects Martin's commitment to honoring its heritage while pushing forward with innovative design. Tonally, the combination of reclaimed spruce, figured koa, and Golden Era scalloped Adirondack bracing produces a powerful and balanced voice with exceptional clarity, strong projection, and rich harmonic content. Whether fingerpicked or strummed, the K-42 Hibiscus offers a dynamic response that rewards a nuanced touch while retaining the headroom needed for aggressive playing styles.
