Martin Custom Shop 45 Style OM Adirondack/Premium Quilted Maple w/case

Serial: 3097576

The Martin Custom Shop 45 Style OM Adirondack/Premium Quilted Maple is an individually configured Orchestra Model that combines exceptional tonewoods, Golden Era construction techniques, and the elaborate pearl appointments associated with Martin's historic Style 45 instruments. Specially configured for Tone Shop Guitars, this instrument features a premium Grade 8 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 quilted figuring of the maple, while extensive select abalone inlays, traditional Style 45 hexagon fingerboard markers, and gold Grover StaTite tuning machines complete a visually striking Custom Shop OM.

The premium Grade 8 Adirondack spruce top provides the foundation for the guitar's acoustic response. Adirondack spruce is prized 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 premium 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 #2, 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 a Style 45 mosaic backstrip, while the Rich Dark Red finish enhances the depth and movement of the quilted figure. Antique white binding and extensive abalone appointments provide a refined contrast against the richly colored maple.

The genuine mahogany 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 gloss neck finish complements the instrument's elegant appearance, and the long diamond volute adds a traditional structural and visual detail.

The black ebony fingerboard features a 16" radius, 20 frets, and traditional Style 45 hexagon inlays crafted from select abalone. These distinctive markers are among the defining visual elements of Martin's most elaborately appointed acoustic guitars. The fingerboard is bound and features carefully mitered appointments, providing a refined transition between the ebony playing surface and antique white binding. The solid headstock features a Pacific Big Leaf Quilted Maple headplate with an inlaid C.F. Martin block logo in select abalone, creating a cohesive connection to the instrument's back and sides. Gold Grover V97-18GA StaTite open-gear tuning machines with vintage-style buttons and an 18:1 gear ratio provide smooth, precise tuning adjustments while complementing the guitar's traditional aesthetic.

The extensive Style 45 pearl work distinguishes this Custom Shop OM from less elaborately appointed instruments. Select abalone perimeter purfling follows the fingerboard profile around the Adirondack spruce top, while additional abalone inlays accent the back, sides, and endpiece. A Style 45 Boltaron rosette with select abalone surrounds the soundhole, creating a coordinated decorative theme throughout the body. Black-and-white Boltaron purfling adds further contrast, while antique white binding frames the guitar's elegant proportions. The clear-finished Adirondack spruce top provides a natural contrast against the Rich Dark Red quilted maple back and sides, and a faux tortoise pickguard reinforces the instrument's traditional Martin styling. The black ebony Golden Era Modern Belly bridge features a compensated bone saddle and bone bridge pins with paua accents, matching the endpin for a cohesive finishing detail.

Built by the Martin Custom Shop in Nazareth, Pennsylvania, this 45 Style OM represents a distinctive combination of premium materials, traditional acoustic construction, and elaborate decorative craftsmanship. Its Adirondack spruce top, Master Grade Deep Quilted Maple back and sides, Golden Era scalloped bracing, and genuine mahogany neck provide a responsive tonal foundation, while the Rich Dark Red finish and extensive abalone appointments 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.
