About This Guitar

This Martin Custom Shop dreadnought was built for Tone Shop Guitars using premium materials and traditional construction techniques. The Italian Alpine spruce top offers clarity, responsiveness, and strong projection, while the exceptional broad figure koa back and sides contribute warmth, complexity, and striking visual character. Together, these woods create a powerful dreadnought voice with articulate highs, rich mids, and a defined low end.

Golden Era hand-shaped scalloped Adirondack bracing and forward-shifted X-bracing enhance responsiveness and headroom, allowing the guitar to react quickly to both fingerstyle and heavy flatpicking. Style 45 appointments—including abalone pearl around the top, back, sides, and rosette—pair with European flamed maple binding and premium koa headplate details to create a refined Custom Shop instrument with both tonal authority and elegant visual presentation.

  • Premium Italian Alpine spruce top with Golden Era scalloped Adirondack bracing
  • Exceptional broad figure koa back and sides selected for Tone Shop NAMM run
  • Full Style 45 abalone pearl appointments throughout the body
