Martin Custom Shop 00-12F 41 Style Adirondack/Exceptional Broad Figure Koa w/case

This Martin Custom Shop 00-12F is an ultra-premium small-body build designed exclusively for Tone Shop Guitars, featuring an Adirondack spruce top paired with Exceptional Broad Figure Koa—one of the most visually and tonally elite tonewood sets available. Its 12-fret Grand Concert design gives it an immediate, open voice with strong fundamental warmth and remarkable responsiveness.

The 41-style aesthetic appointments elevate this guitar into heirloom territory: perimeter abalone top trim, Style-45 abalone rosette, alternate torch inlays, and antique white binding create a refined, vintage-inspired presentation. Every element—from the hide-glue dovetail neck joint to the Waverly gold tuners—reflects top-tier handcrafting from the Martin Custom Shop. This instrument is both a showpiece and a deeply expressive player’s guitar.
