The Martin Custom Shop 18 Style Adirondack Spruce-Mahogany Herringbone Dreadnought acoustic guitar brings together classic design and high-end materials for a rich, focused sound. Built with a dreadnought 14-fret body, it features an Adirondack spruce top and mahogany back and sides, finished in gloss. The herringbone top inlay and abalone snowflake fingerboard markers add visual detail. Forward-shifted X-bracing improves dynamic response, and the modified low oval neck feels comfortable during long sessions. This model works well for players who want clear projection and a guitar that responds to detailed playing. The included hardshell case makes it easy to transport the instrument safely between sessions and performances.

Adirondack Spruce Top and Forward-Shifted X-Bracing Create Dynamic Tone

The dreadnought's top uses Adirondack spruce, known for its stiffness and powerful sound. The forward-shifted X-bracing pattern increases the top's vibration, providing more volume and stronger bass. Adirondack braces keep the top stable while letting it ring out. Players can expect a guitar that projects well in group settings or when played solo. The spruce top helps deliver crisp notes that don't get lost in a mix.

Mahogany Back and Sides Provide Focused, Balanced Response

Mahogany on the back and sides gives the guitar a clear, woody character. The gloss finish brings out the natural grain and protects against wear. Black binding and HD zig zag purfling frame the body, while the Style 28 rosette adds a subtle touch around the soundhole. Notes sound tight, with a fast attack that suits intricate fingerstyle or rhythmic strumming. Mahogany's warmth and focus make it easy to hear every detail in your playing.

Thoughtful Neck and Fingerboard Design Improves Playability

The select hardwood neck uses a modified low oval profile, making it easy to grip. An ebony fingerboard feels smooth and resists wear. With a 1-3/4" nut width and 20 frets, players can move across the neck with little effort. Abalone snowflake inlays help guide the hand without distraction. Waverly nickel tuners keep tuning stable, and the long bone saddle improves sustain and intonation. The satin finish on the neck reduces friction for comfortable shifts between chords and scales.

Durable Build Protects Against Long-Term Damage

This acoustic guitar uses a dovetail neck joint for strength and alignment. The modern belly bridge and bone saddle keep string spacing consistent. White bridge and end pins with faux tortoise details match the faux tortoise pickguard. Authentic Acoustic Lifespan 2.0 strings offer extended life and stable tone. The included hardshell case shields the guitar from bumps and climate changes during transport.
