Martin Custom Shop 18 Style 00-12F Adirondack/Sinker Mahogany w/case 3053227

Built exclusively through the Martin Custom Shop for Tone Shop Guitars, this 18 Style 00-12F combines vintage-inspired design with premium tonewoods and elegant understated appointments. Featuring a compact 12-fret 00 body, Adirondack spruce top, and sinker mahogany back and sides, this custom model delivers exceptional responsiveness, warmth, and clarity with a rich, woody character that suits fingerstyle players and light-to-medium flatpickers alike.

The 12-fret design shifts the bridge deeper into the lower bout, enhancing resonance, sustain, and low-end fullness while preserving the focused articulation and intimate feel that make 00-sized Martins so beloved. Golden Era hand-shaped scalloped Adirondack bracing adds openness and dynamic sensitivity, while the sinker mahogany body contributes dry vintage-style warmth and quick note response.

Finished with classic Style 18 appointments including faux tortoise binding, Diamonds & Squares Long fingerboard inlays, slotted headstock, ebony fingerboard and bridge, and an aging toner top, this Custom Shop build blends old-world Martin aesthetics with refined modern playability.
