Martin O'ahu K-42 Hibiscus Acoustic Guitar - Dark Toast Burst (#26 of 100) | No Limit Guitar Co, Idaho Falls
The Martin O'ahu K-42 Hibiscus is a limited-edition acoustic guitar rooted in Hawaiian musical tradition and built to Martin's highest standard of craftsmanship — and this is number 26 of just 100 instruments ever made, now available at No Limit Guitar Co in Idaho Falls. Its historic Kealakai body pairs reclaimed Sitka spruce with highly figured koa back and sides, producing a voice that is powerful, lush, and deeply expressive across the full dynamic range. From the Adirondack spruce Golden Era bracing to the Aulson Inlay hibiscus fingerboard work, every element of this guitar reflects a rare convergence of island heritage and elite lutherie.
Product Overview
The Kealakai body silhouette is one of the most historically significant in acoustic guitar design — wider and deeper than a traditional 000, it was originally created in 1916 to fill concert halls without amplification, pioneering the expanded internal air volume that would later influence the dreadnought. Martin's O'ahu K-42 Hibiscus revives this platform with a 14-fret neck and forward-shifted Golden Era scalloped X-bracing in Adirondack spruce, treated with Martin's Vintage Tone System to give the reclaimed top the openness and immediacy of a well-aged vintage instrument. The result is commanding low-end presence, refined note separation, and a dynamic range suited to both fingerstyle expressiveness and full-bodied strumming.
The reclaimed Sitka spruce top is sourced from old-growth wind-felled timber, historic bridges, and marine logging infrastructure surrounding Prince of Wales Island, Alaska — material whose exceptional stiffness-to-weight ratio yields strong projection, quick transient response, and rich harmonic complexity. Highly figured koa back and sides contribute warmth, sparkle, and a blooming midrange that complements the spruce top's clarity and projection. The Dark Toasted Burst gloss finish deepens the vintage character of the reclaimed top while showcasing the natural grain and koa's dramatic flame figuring on the back and sides.
A genuine mahogany neck in Martin's GE Modified Low Oval profile with High-Performance Taper provides modern comfort and fluid playability across the 25.4" scale length. The ebony fingerboard features an intricate hibiscus inlay by Aulson Inlay — a handcrafted tribute to the Hawaiian roots of the O'ahu collection — and is Plek'd for precision setup at 1-3/4" nut width across 20 frets. Hardware appointments reflect Martin's Style 45 tier: Waverly gold open-gear tuners with Liquidmetal posts and abalone dots, a modern belly pyramid ebony bridge with bone saddle and Liquidmetal bridge pins, and Style 45 abalone purfling and multi-stripe rosette throughout.

Key Features
Historic Kealakai Body with Golden Era Scalloped X-Bracing The Kealakai silhouette — wider and deeper than a 000 — was designed in 1916 to project unamplified into concert halls, and its expanded internal air volume remains one of the most resonant body shapes in acoustic guitar history. Golden Era Adirondack spruce scalloped X-bracing treated with Martin's Vintage Tone System allows the reclaimed top to open up with the depth and immediacy of a played-in vintage instrument.
Reclaimed Sitka Spruce Top Salvaged from old-growth timber and historic marine infrastructure around Prince of Wales Island, Alaska, the reclaimed Sitka spruce top offers a stiffness-to-weight ratio and harmonic maturity rarely found in newly harvested wood. The material's age and density contribute to the projection, dynamic headroom, and tonal complexity the K-42 Hibiscus delivers at full volume.
Highly Figured Koa Back and Sides Hawaiian koa is celebrated for its warmth, sparkle, and distinctive midrange bloom — tonal qualities that pair naturally with Sitka spruce's clarity and projection. The highly figured back and sides also make each instrument visually unique, with dramatic flame patterns that deepen the guitar's collector appeal.
Hibiscus Fingerboard Inlay by Aulson Inlay The ebony fingerboard features an intricate hand-crafted hibiscus design inlaid by Aulson Inlay, honoring the Hawaiian cultural roots of the O'ahu collection. The design is one of the most visually distinctive fingerboard inlay commissions in Martin's modern catalog.
Liquidmetal Hardware and Waverly Gold Tuners Liquidmetal bridge pins and tuner posts enhance sustain, resonance transfer, and clarity at the bridge and headstock. Waverly gold open-gear tuners with butterbean knobs and abalone dots provide smooth, precise tuning with the aesthetic of a vintage instrument and the reliability of modern engineering.
Style 45 Abalone Appointments Throughout Style 45 abalone purfling, multi-stripe rosette, top inlays, back purfling, and side inlay establish the K-42 Hibiscus at Martin's highest tier of decorative craftsmanship. Madagascar rosewood binding, heelcap, and endpiece with multi-stripe inlay complete a presentation that is both historically informed and visually extraordinary.
