Martin Custom Shop OM 'Premium Sitka / Mahogany Ambertone' Acoustic Guitar

Hand selected by Acoustic Centre at the Martin Guitars Custom Shop in Nazareth, Pennsylvania, this Martin Custom Shop OM blends vintage elegance with the tonal balance that has defined Martin craftsmanship for over a century. Built with a premium Sitka spruce top and genuine mahogany back and sides, it delivers a clear, warm and articulate tone with exceptional projection and balance across all registers, while the Ambertone 1933 finish adds a touch of old-world character.

Scalloped ¼" Sitka bracing brings responsiveness, and a comfortable Modified Low Oval neck keeps the OM feeling lively and resonant in the hands. Its slotted headstock, ebony fingerboard and rosewood binding reflect Martin's rich heritage. It's ideal for players seeking timeless tone, refined aesthetics and the unmistakable feel of a hand-crafted instrument, built with the understated appointments that define the OM tradition.
