Martin Custom Shop 28/45 Style OM Adirondack/Cocobolo w/case 3068305

The Martin Custom Shop 28/45 Style OM Adirondack/Cocobolo is a premium Tone Shop Guitars exclusive that combines the legendary responsiveness of an Orchestra Model with the luxurious aesthetics of Style 45 appointments and the extraordinary tonal character of premium Cocobolo. Built around a hand-selected Adirondack spruce top and premium Cocobolo back and sides, this custom instrument offers exceptional projection, harmonic richness, and dynamic headroom for discerning players.

Adirondack spruce provides powerful articulation, outstanding clarity, and tremendous headroom, while Cocobolo delivers deep bass response, brilliant highs, and rich overtone complexity that rivals the finest rosewoods. The Golden Era hand-shaped scalloped Adirondack bracing enhances responsiveness and resonance, creating a remarkably expressive instrument equally suited for fingerstyle, flatpicking, and sophisticated accompaniment work.

The GE Modified Low Oval neck profile with High Performance Taper offers modern comfort while preserving vintage-inspired feel. Elegant Style 45 appointments—including select abalone rosette work, Style 45 Reduced Hexagon fingerboard inlays, aging toner top, and premium Cocobolo appointments—make this OM as visually impressive as it is sonically inspiring.
