Martin 00-18 Acoustic Guitar

The Martin 00-18 is a classic Grand Concert acoustic guitar that combines a solid spruce top with solid mahogany back and sides to deliver a clear, balanced, and highly responsive tonal character. Its compact 00-14 Fret body produces a focused voice with articulate trebles, punchy mids, and warm low-end response, making it especially well suited to fingerstyle playing, songwriting, recording, and intimate acoustic performance.

The 00-18 features Martin's Golden Era (GE) scalloped X-bracing, which enhances the responsiveness, resonance, sustain, and harmonic detail of the spruce soundboard. Its 24.9-inch short scale provides a comfortable playing feel, while the GE Modified Low Oval neck profile, High-Performance Taper, and 1 3/4-inch nut width offer excellent control and room for expressive fingerstyle technique.

The guitar features an aging-toned gloss spruce top, dark mahogany gloss back and sides, an ebony fingerboard and bridge, Old Style 18 abalone dot inlays, black binding, and a faux tortoise pickguard. Nickel open-gear tuning machines with butterbean knobs and an Old Style 18 multi-stripe rosette complete its traditional appearance. The 00-18 comes with a hardshell case and Martin Authentic Acoustic Lifespan® 2.0 Phosphor Bronze Light strings.
