Martin Custom Shop 28 Style OM Adirondack/Premium Quilted Maple w/case

Serial: 3097577

The Martin Custom Shop 28 Style OM Adirondack/Premium Quilted Maple is an individually configured Orchestra Model that combines premium tonewoods, Golden Era construction techniques, and traditional Style 28 appointments with a striking custom finish. Specially configured for Tone Shop Guitars, this instrument features an Adirondack spruce top, hand-selected Master Grade Deep Quilted Maple back and sides, and hand-shaped Golden Era scalloped Adirondack spruce bracing. Its distinctive Rich Dark Red finish highlights the dramatic figuring of the maple, while bold herringbone top purfling, select abalone inlays, and nickel Grover StaTite tuning machines complete a refined interpretation of Martin's classic OM design.

The Adirondack spruce top provides the foundation for the guitar's acoustic response. Adirondack spruce is valued for its strength, dynamic headroom, and ability to maintain clarity across a wide range of playing dynamics. Its responsive character makes it particularly well suited to the Orchestra Model platform, where balance, articulation, and sensitivity are essential. The top is supported by 1/4" Golden Era scalloped X-bracing, crafted from Adirondack spruce and individually hand-shaped to enhance the soundboard's movement. This construction encourages a responsive acoustic voice with strong note separation, clear projection, and a broad dynamic range. The combination of Adirondack spruce and Golden Era bracing makes this guitar particularly appealing for fingerstyle playing, intricate chord voicings, and articulate flatpicking.

The back and sides are crafted from premium Deep Quilted Maple selected specifically for this Tone Shop Guitars Custom Shop build. Identified as Master Grade Deep Quilt Maple #7, this exceptional wood selection features dramatic three-dimensional figuring that creates a distinctive visual texture across the instrument. Maple is known for its clear, focused tonal response, articulate midrange, and controlled overtones, making it an excellent complement to the powerful Adirondack spruce top. The combination provides a balanced acoustic voice with strong note definition, quick response, and excellent clarity across complex chord voicings. The two-piece maple back features traditional spruce bracing and an HD-style zigzag backstrip, while the Rich Dark Red finish enhances the depth and movement of the quilted figure. Antique white binding provides a refined contrast against the richly colored maple.

The select hardwood neck features Martin's Golden Era Modified Low Oval profile with a High Performance Taper, combining traditional neck shaping with a comfortable, streamlined playing feel. Its 1 3/4" nut width provides generous string spacing for fingerstyle techniques, while the 2 5/32" bridge string spacing supports precise control over individual strings. The 25.4" scale length delivers the familiar tension, articulation, and projection associated with Martin's long-scale Orchestra Models. A traditional dovetail neck joint creates a strong acoustic connection between the neck and body, while the adjustable truss rod allows precise neck relief adjustments. The satin neck finish offers a smooth playing surface, and the long diamond volute adds a traditional structural and visual detail.

The black ebony fingerboard features a 16" radius, 20 frets, and traditional long-pattern Diamonds and Squares inlays crafted from select abalone. These distinctive markers reflect Martin's historic Style 28 design language while adding a refined Custom Shop touch. The unbound fingerboard maintains a traditional appearance, complemented by white side position markers for easy reference. The solid headstock features a polished black ebony headplate with an inlaid C.F. Martin block logo in select abalone, providing a premium alternative to a standard headstock decal. Nickel Grover V97-18NA StaTite open-gear tuning machines with vintage-style buttons and an 18:1 gear ratio offer smooth, precise tuning adjustments while complementing the guitar's traditional aesthetic.

The visual appointments balance classic Martin styling with the distinctive character of the custom quilted maple construction. Bold herringbone purfling frames the clear-finished Adirondack spruce top, while a Style 45 Boltaron rosette with select abalone surrounds the soundhole. Antique white body binding, a faux tortoise pickguard, and the traditional HD-style zigzag backstrip reinforce the guitar's vintage-inspired appearance. The Rich Dark Red finish provides a striking contrast against the natural spruce top, allowing the dramatic quilted figuring of the maple back and sides to remain a defining visual feature. The black ebony Golden Era Modern Belly bridge features a compensated bone saddle and bone bridge pins with faux tortoise accents, matching the endpin for a cohesive finishing detail.

Built by the Martin Custom Shop in Nazareth, Pennsylvania, this 28 Style OM represents a distinctive combination of premium materials, traditional acoustic construction, and carefully selected custom appointments. Its Adirondack spruce top, Master Grade Deep Quilted Maple back and sides, Golden Era scalloped bracing, and comfortable Modified Low Oval neck provide a responsive tonal foundation, while the Rich Dark Red finish and select abalone details establish a unique Custom Shop identity. The guitar is entirely acoustic, without onboard electronics, preserving its traditional construction and natural resonance. A five-ply hardshell case and Martin Custom Shop Credentials Book are included, completing an individually configured instrument that showcases the beauty of exceptional quilted maple and the craftsmanship of Martin's Custom Shop.
