Martin GPC-13E Modern Koa

The Martin GPC-13E Modern blends contemporary style with stage-ready performance in a versatile Grand Performance cutaway design. A solid spruce top pairs with koa fine-veneer back and sides to produce a balanced voice with shimmering highs, rich mids, and supportive low end. Scalloped X-bracing enhances projection and responsiveness, while the GP-14 body shape offers a focused, articulate tonal profile well-suited for strumming, fingerstyle, and modern acoustic playing.

A Performing Artist neck with high-performance taper ensures smooth, fast playability, complemented by diamond-and-square long inlays and Ratio nickel open-gear tuners. With onboard Martin E1 electronics, a built-in tuner, and a softshell case, the GPC-13E Modern is ready to perform anywhere your music takes you.
