The Martin Custom Shop OM Style 45 All Koa acoustic guitar is a stunning orchestral model featuring hand-selected flamed koa throughout the entire body. Known for its bright, warm tone, koa opens up over time, providing richer overtones and increased resonance. Outlined in European flame maple binding and adorned with a premium 45-style rosette, this elegant guitar delivers on both sound and appearance, making it perfect for discerning players and collectors alike.

Flamed Koa for Bright, Warm Tone

The all-koa construction of this Custom Shop OM produces a bright, articulate sound that grows richer with time. The unique tonal qualities of koa combine warmth and clarity, while the flamed grain of the wood gives this guitar a striking visual appeal. Whether you’re fingerpicking or strumming, the koa delivers a balanced tone with plenty of projection.

European Flame Maple Binding and Premium Rosette

The visual elegance of this guitar is enhanced by the European flame maple binding, which outlines the body in a stunning contrast to the koa. The 45-style abalone rosette adds a further touch of class, making this instrument as much a work of art as it is a musical tool. These luxurious details elevate the guitar’s appearance, ensuring it stands out on any stage.

High-End Appointments for Exceptional Playability

Equipped with Martin's ebony bridge and fretboard, this guitar offers smooth playability and a sleek feel. The fretboard is inlaid with abalone diamonds and squares, adding to the instrument’s ornate design. Gold Schaller tuners provide precision tuning with smooth action, ensuring that this guitar performs flawlessly, whether in the studio or on stage.
