Martin Custom Shop 0-18 Adirondack Spruce Acoustic Guitar - Natural

Answering player demand for a premium 0-size acoustic, the Martin Custom Shop 0-18 acoustic guitar brings Golden Era-inspired construction and high-end tonewoods to a compact 14-fret Concert format. A solid Adirondack spruce top with aging toner pairs with genuine mahogany back and sides for clear trebles, punchy midrange and a focused low end that suits fingerstyle, songwriting and recording. Hand-shaped Adirondack Golden Era scalloped X-bracing enhances resonance and dynamic response, while the 24.9" short scale and GE Modified Low Oval neck profile create a relaxed, vintage-inspired feel. Finished in vintage gloss with Old Style 18 appointments, this Custom Shop model offers refined Martin craftsmanship in an intimate, expressive acoustic built for serious players.

Premium Tonewoods in a Focused 0-Size Body

The Custom Shop 0-18 pairs an Adirondack spruce top with genuine mahogany back and sides, a classic Martin tonewood combination shaped here for the smaller 0-14 fret body. Adirondack spruce contributes clarity, headroom and dynamic range, giving the guitar room to respond whether played softly or with a stronger attack. Mahogany adds dry warmth, midrange punch and a focused low end, helping each note stay articulate in fingerstyle passages, vocal accompaniment and close-miked recording environments. Compact, balanced and immediate, this 0-size acoustic rewards players who value touch sensitivity over sheer volume.

Golden Era Bracing for Vintage-Inspired Response

Hand-shaped Adirondack Golden Era scalloped X-bracing gives the Custom Shop 0-18 a responsive foundation rooted in traditional Martin design. The 1/4" braces help the top move freely while maintaining the definition needed for clean note separation and controlled sustain. This bracing approach is especially effective in a small-body guitar, where responsiveness and balance are central to the playing experience. The result is a compact acoustic with a lively attack, nuanced dynamic range and the refined resonance players expect from Martin Custom Shop construction.

Short-Scale Comfort With Custom Shop Playability

The 24.9" scale length gives the Custom Shop 0-18 a slightly softer string feel than a long-scale acoustic, making chord work, bends and expressive fingerstyle phrasing feel more relaxed. A genuine mahogany neck with a GE Modified Low Oval profile and High Performance Taper balances vintage-inspired comfort with modern playability, while the 1.75" bone nut provides room for clean fretting-hand accuracy. A Plek setup further supports consistent response across the 20-fret ebony fingerboard, making this small-body Martin feel refined, approachable and performance-ready.

Old Style 18 Appointments and Vintage Gloss Finish

Visually, the Custom Shop 0-18 draws from Martin’s understated Style 18 tradition while adding refined Custom Shop detail. The aging toner top, dark mahogany back and sides, vintage gloss body and neck finish create a classic, time-honored appearance without feeling overly ornate. Faux tortoise binding, faux tortoise pickguard and an Old Style 18 multi-stripe rosette reinforce the traditional aesthetic, while abalone fingerboard inlays add a subtle touch of elegance. Ebony for the fingerboard and bridge, bone for the nut and saddle, and nickel open-gear tuners complete a build that feels purposeful from top to bottom.

A Gateway to Martin Custom Shop Craftsmanship

An enticing entry point into Martin’s Custom Shop lineup, the Custom Shop 0-18 combines premium tonewoods, Golden Era-inspired construction and the intimate feel of a compact 0-size body. Its focused voice, quick response and refined note separation make it especially compelling for fingerstyle players, songwriters and recording musicians who want a guitar that captures detail without overwhelming a mix. Complete with a hardshell case, the Martin Custom Shop 0-18 acoustic guitar delivers heirloom-level craftsmanship in a responsive, player-friendly format.
