Martin Custom Shop Limited Edition O'ahu K-42 Hibiscus w/case

Martin Custom Shop O’ahu K-42 Hibiscus – Limited Edition

A breathtaking fusion of Martin heritage, Hawaiian artistry, and modern innovation, the Martin O’ahu K-42 Hibiscus reimagines one of the most important body designs in acoustic guitar history. Inspired by the historic Kealakai instruments that helped shape the dreadnought’s origins, this limited-edition masterpiece blends deep tradition with forward-thinking craftsmanship.

At the heart of the K-42 Hibiscus is a K-sized 12-fret body paired with a 14-fret neck, an unprecedented first for Martin. This unique configuration delivers enhanced projection, clarity, and balance while retaining the deep, powerful voice associated with Martin’s earliest large-body acoustics. A reclaimed Sitka spruce top, finished in a striking dark toasted burst, is paired with figured broad-flamed koa back and sides, producing a rich, articulate tone with shimmering overtones and warm low-end depth.

Visually, this instrument is nothing short of extraordinary. Ornate hibiscus inlays, elegant Style 42 appointments, and Madagascar rosewood binding elevate the K-42 Hibiscus into true collector-grade territory. Premium hardware, including Waverly® gold tuning machines with Liquidmetal® posts, ensures smooth, precise tuning while complementing the guitar’s luxurious aesthetic.

Produced in an extremely limited run of just 100 guitars worldwide, the Martin O’ahu K-42 Hibiscus stands as a celebration of artistry, innovation, and legacy—an heirloom-quality instrument designed for discerning players and collectors alike.
