Martin Custom Shop 28 Style OM Adirondack/Wild Grain East Indian Rosewood Ambertone 3078239
About This Guitar
Serial: 3078239
Designed through the Martin Custom Shop for Tone Shop Guitars, this OM pairs an Adirondack spruce top with premium Wild Grain East Indian rosewood back and sides selected by Tone Shop. It takes the foundation of a Style 28 OM and adds a carefully chosen mix of Golden Era-inspired construction and premium appointments.
The Adirondack spruce top is supported by forward-shifted, scalloped 1/4" Adirondack bracing with Golden Era hand shaping. Combined with the OM body and 25.4" scale length, the result is a build centered around the responsiveness, balance, and dynamic range that make the OM format such a versatile Martin design.
The Wild Grain East Indian rosewood back and sides give this guitar a particularly striking visual identity, complemented by bold herringbone top inlay, Antique White binding, a Style 28 rosette, and an Aging Toner top beneath a gloss body finish.
The GE Modified Low Oval neck uses Martin’s High Performance Taper and a 1-3/4" nut width, paired with a black ebony fingerboard and long Diamonds and Squares inlays. Grover Sta-Tite tuners, an ebony GE Modern Belly bridge, bone nut and compensated bone saddle complete the build.
A 5-ply hardshell case and Martin Custom Shop Credentials Book are included.
