This exquisite Custom Shop Martin blends vintage elegance with modern precision. Built on a 000/OM body, it features a Premium Engelmann Spruce top (Aging Toner finish) paired with luxurious Cocobolo back/sides, delivering rich, balanced tones with sparkling clarity. The Golden Era scalloped bracing and 25.4" scale optimize resonance, while Style 45 Snowflake inlays (abalone) and a Boltaron rosette elevate its visual allure. Playability shines with a Modified Low Oval mahogany neck, ebony fingerboard (1¾" nut), and Waverly Gold tuners. Finished in gloss with antique white binding, this masterpiece is a fingerstylist’s dream—unplugged, uncompromising, and utterly collectible.
