Overview

An auditorium acoustic with rich tone and striking mahogany grain.

The Martin Custom Shop 18 Style Adirondack Spruce-Flamed Mahogany Auditorium acoustic guitar blends classic auditorium proportions with striking visual and tonal elements. Adirondack spruce forms the top, paired with premium flamed mahogany for the back and sides. The gloss finish shows off the wood's figure, while old style 18 details like the rosette and fingerboard inlays connect the guitar to Martin's history. The 000 auditorium size sits comfortably in your lap, making it easy to play for hours. Players who want clear note separation and a quick response will appreciate the tight bracing and tailored neck profile. With no electronics or cutaways, this model keeps focus on the pure acoustic experience, suited for recording, practice or live acoustic shows.

Flamed Mahogany Adds Richness and Depth

Premium flamed mahogany on the back and sides adds warmth and visual flair. The tight grain and flame pattern stand out under the gloss finish. Mahogany shapes the guitar's midrange, giving chords a focused sound. The wood's resonance also supports smooth sustain, so notes blend together in a natural way. This material choice creates a lively response without sounding harsh.

Adirondack Spruce Top and X-Bracing Shape Projection

Adirondack spruce, known for its stiffness and light weight, forms the top. The X-brace pattern underneath helps the top vibrate evenly, so every note rings clear. The spruce bracing increases volume and sustain, making this acoustic guitar project well in small venues. Players get a fast response with clear attack, which supports precise fingerpicking and clean strumming.

Modern Belly Bridge and Grover Nickel Tuners Improve Usability

Players adjust intonation and action easily with the modern belly bridge and bone saddle. Grover nickel tuners hold pitch steady through long sessions. The faux tortoise pickguard protects the top without distracting from the look. The 1-3/4" nut width and modified low oval neck offer space for fingerstyle and comfort for long sets. Ebony fingerboard feels smooth and resists wear over time.

Gloss Finish and Dovetail Neck Joint Support Longevity

The gloss finish on the top, back and sides seals the wood and keeps it looking new. The dovetail neck joint connects neck and body tightly, reducing movement and extending the life of the guitar. Bone nut and saddle resist string wear, while black binding protects the edges. The included hardshell case shields the instrument during travel and storage.
