{"product_id":"gpc-13e-modern-fg-spr-koafv-w-ss","title":"Martin GPC-13E Modern Road Series Grand Performance Acoustic-Electric Guitar","description":"\u003ch2\u003eA Stage-Ready Martin That Does a Lot of Things Well\u003c\/h2\u003e\n\u003cp\u003eThere's a certain sweet spot in guitar design where size, shape, and tonewoods all click into place at once. Martin's GPC-13E Modern lands right in it. The Grand Performance cutaway body is roomy enough to produce real depth and projection, but its contoured waist and comfortable reach make it feel genuinely playable all night long — whether you're working through a full set or chasing ideas at home.\u003c\/p\u003e\n\u003cp\u003eThe combination of a solid spruce top with koa fine veneer back and sides gives this guitar a clear, balanced voice with shimmering highs and focused midrange. Scalloped X-bracing underneath the top helps maximize volume and responsiveness, so the guitar projects well without feeling forced. Add Martin E1 onboard electronics, and you have one guitar that's equally at home unplugged and plugged into a PA.\u003c\/p\u003e\n\u003cp\u003eThis is a strong choice for singer-songwriters, working gigging players, and anyone who needs a versatile acoustic-electric that can handle fingerpicking, strumming, and everything in between — all without breaking the bank on a custom-shop build.\u003c\/p\u003e\n\n\u003ch2\u003eSolid Spruce Top with Koa Fine Veneer Back \u0026amp; Sides\u003c\/h2\u003e\n\u003cp\u003eThe top here is solid spruce — Martin's official spec page and multiple approved retailers confirm it — which means the vibrating surface at the heart of the guitar's voice is real, resonant tonewoods doing real work. Solid tops respond and open up over time in a way laminates typically don't. The scalloped X-bracing pattern further enhances that responsiveness, giving the guitar lively volume and dynamic range across playing styles.\u003c\/p\u003e\n\u003cp\u003eThe back and sides are koa fine veneer, finished with a cherry stain that brings out koa's natural shimmer and warmth. Koa's tonal character leans toward balanced mids and sparkly highs — complementing the spruce top nicely and keeping the overall voice clear rather than boomy. The gloss finish on both top and body gives the guitar a clean, polished look that holds up on stage.\u003c\/p\u003e\n\n\u003ch2\u003eA Neck Built for Speed and Comfort\u003c\/h2\u003e\n\u003cp\u003eMartin's Performing Artist neck profile with high-performance taper is one of the defining features of the Road Series Modern lineup. It's slimmer and more tapered than a traditional acoustic neck, which makes a real difference for players who spend a lot of time on single-note runs, leads, or complex chord voicings. The 16-inch fingerboard radius and 1 3\/4\" nut width keep things comfortable across all positions.\u003c\/p\u003e\n\u003cp\u003eThe ebony fingerboard is smooth and stiff — a contact surface that contributes to clarity and sustain at every fret. Diamond-and-square long inlays dot the fingerboard with visual interest, while the mortise and tenon neck joint provides a solid, stable connection between neck and body. The neck carries a hand-applied finish, so it never feels sticky or slow under the fretting hand. Scale length is the standard Martin 25.4\".\u003c\/p\u003e\n\n\u003ch2\u003eMartin E1 Electronics — Simple, Effective, Gig-Ready\u003c\/h2\u003e\n\u003cp\u003eThe E1 pickup system is mounted inside the soundhole, keeping the exterior of the guitar completely clean — no side-mounted preamp boxes or control panels to interfere with the acoustic look or feel. Controls include volume, tone, and a phase-reverse switch, along with a built-in chromatic tuner that lets you tune silently without unplugging. It's a practical, no-fuss setup for live performance.\u003c\/p\u003e\n\u003cp\u003eWhether you're running into an acoustic amplifier, directly into a venue PA, or through an interface for recording, the E1 system captures the guitar's natural tonal balance and passes it along faithfully. The Corian nut and TUSQ saddle help purify string response at the contact points, which contributes to cleaner amplified tone as well as acoustic resonance.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Features:\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTop:\u003c\/strong\u003e Solid spruce, gloss finish, scalloped X-bracing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack \u0026amp; Sides:\u003c\/strong\u003e Koa fine veneer with cherry stain, gloss finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape:\u003c\/strong\u003e Grand Performance cutaway (GP-14 fret)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck:\u003c\/strong\u003e Select hardwood, Performing Artist profile with high-performance taper, hand-applied finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFingerboard:\u003c\/strong\u003e Ebony, 16\" radius, 20 frets, 1 3\/4\" nut width, Diamond and Square Long inlays\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScale Length:\u003c\/strong\u003e 25.4\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut \/ Saddle:\u003c\/strong\u003e Corian nut, TUSQ saddle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElectronics:\u003c\/strong\u003e Martin E1 with volume, tone, phase-reverse, and built-in chromatic tuner\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTuners:\u003c\/strong\u003e Ratio® skeletonized nickel open-gear tuners\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBinding:\u003c\/strong\u003e White body binding; faux abalone single-ring rosette\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Joint:\u003c\/strong\u003e Mortise and tenon\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e Martin\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eModel:\u003c\/strong\u003e GPC-13E Modern\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSKU:\u003c\/strong\u003e 11GPC13EMOD\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e New\u003c\/p\u003e\n\n\u003cp\u003eSince 1872, C.A.
