On our latest deep-space haul, the Interstellar Tone Traveler touched down on something genuinely rare: the Martin Super D-18, a bold evolutionary leap from the legendary Style 18 lineage that takes everything we love about mahogany dreadnoughts and dials it up to eleven. The Super D body packs 20% more internal air volume than a standard Dreadnought, and you feel that difference the moment you strum — thunderous low-end, extended dynamic range, and a volume that commands the room without ever losing the warm, punchy character that makes mahogany so irresistible. This is the D-18 that dares to dream bigger.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eUnder the hood, Martin didn't just scale up the body and call it a day. Forward-shifted Golden Era scalloped X-bracing — borrowed directly from the Modern Deluxe Series — makes every note bloom with responsiveness, while the solid spruce top delivers the clarity and projection to cut through any sonic atmosphere. An ebony fingerboard and bridge add refinement and snap to the low-end foundation, and the satin-finished mahogany neck keeps your hand moving freely all night long. Black binding, Old Style 18 abalone inlays, and a Faux Tortoise pickguard keep the aesthetic grounded and classic — no flash, just function elevated to art. For players who need to be heard across the galaxy, the Super D-18 is your ship.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cb\u003eTop:\u003c\/b\u003e Spruce \u003cbr\u003e\u003cb\u003eFinish Top:\u003c\/b\u003e Gloss\u003cbr\u003e\u003cb\u003eTop Color: \u003c\/b\u003eAging\u003cb\u003e \u003c\/b\u003eToner\u003cbr\u003e\u003cstrong\u003eTop Inlay Material:\u003c\/strong\u003e Multi-Stripe\u003cbr\u003e\u003cstrong\u003eTop Detail:\u003c\/strong\u003e None\u003cbr\u003e\u003cb\u003eBinding:\u003c\/b\u003e Black\u003cbr\u003e\u003cb\u003eBridge Material:\u003c\/b\u003e Ebony\u003cbr\u003e\u003cb\u003eBridge Style:\u003c\/b\u003e GE Modern Belly - Drop in Saddle\u003cbr\u003e\u003cb\u003eBridge String Spacing:\u003c\/b\u003e \u003cspan\u003e2 5\/32\"\u003c\/span\u003e\u003cbr\u003e\u003cb\u003eBridge Pin Material:\u003c\/b\u003e Ebony\u003cbr\u003e\u003cstrong\u003eBridge Pin Dots:\u003c\/strong\u003e None\u003cbr\u003e\u003cstrong\u003ePickguard:\u003c\/strong\u003e Faux Tortoise \u003cbr\u003e\u003cstrong\u003ePickguard Inlay:\u003c\/strong\u003e None\u003cbr\u003e\u003cstrong\u003eRosette:\u003c\/strong\u003e Old Style 18 Multi-Stripe\u003cbr\u003e\u003cstrong\u003eSaddle:\u003c\/strong\u003e Bone\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eSaddle Radius:\u003c\/strong\u003e 16\"\u003cbr\u003e\u003cstrong\u003eBody Size:\u003c\/strong\u003e Super D-14 Fret\u003cbr\u003e\u003cstrong\u003eConstruction:\u003c\/strong\u003e Dovetail Neck Joint \u003cbr\u003e\u003cstrong\u003eBack Material:\u003c\/strong\u003e Genuine Mahogany\u003cbr\u003e\u003cb\u003eSide Material:\u003c\/b\u003e Genuine Mahogany \u003cbr\u003e\u003cb\u003eBody Finish:\u003c\/b\u003e Gloss\u003cbr\u003e\u003cb\u003eBack Purfling\/Strip:\u003c\/b\u003e Style 18\u003cbr\u003e\u003cb\u003eBack Inlay Material:\u003c\/b\u003e None\u003cbr\u003e\u003cb\u003eBracing Pattern:\u003c\/b\u003e \u003cspan\u003eForward Shifted X-Brace\u003c\/span\u003e\u003cbr\u003e\u003cb\u003eBrace Shape:\u003c\/b\u003e GE-Scalloped\u003cbr\u003e\u003cstrong\u003eBrace Material:\u003c\/strong\u003e Spruce \u003cbr\u003e\u003cstrong\u003eBrace SIze:\u003c\/strong\u003e 5\/16\"\u003cbr\u003e\u003cstrong\u003eHeel Cap:\u003c\/strong\u003e Black\u003cbr\u003e\u003cstrong\u003eEndpiece:\u003c\/strong\u003e Black\u003cbr\u003e\u003cstrong\u003eEndpiece Inlay:\u003c\/strong\u003e None\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eNeck Shape:\u003c\/strong\u003e GE Modified Low Oval\u003cbr\u003e\u003cstrong\u003eNeck Taper:\u003c\/strong\u003e High-Performace Taper\u003cbr\u003e\u003cstrong\u003eNeck Material:\u003c\/strong\u003e Mahogany \u003cbr\u003e\u003cstrong\u003eNeck Color:\u003c\/strong\u003e Dark Mahogany\u003cbr\u003e\u003cb\u003eNeck Finish:\u003c\/b\u003e Satin\u003cbr\u003e\u003cstrong\u003eScale Length:\u003c\/strong\u003e 25.4\"\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eNumber of Frets:\u003c\/strong\u003e 20\u003cbr\u003e\u003cstrong\u003eNeck Joins Body:\u003c\/strong\u003e 14 Fret\u003cbr\u003e\u003cstrong\u003eFingerboard Material:\u003c\/strong\u003e Ebony\u003cbr\u003e\u003cstrong\u003eFingerboard Width at 12th Fret:\u003c\/strong\u003e 2 1\/8\"\u003cbr\u003e\u003cb\u003eNut Width:\u003c\/b\u003e 1 3\/4\"\u003cbr\u003e\u003cstrong\u003eInlay Style:\u003c\/strong\u003e Old Style 18 \u003cbr\u003e\u003cstrong\u003eFingerboard Inlay Material:\u003c\/strong\u003e Abalone\u003cbr\u003e\u003cstrong\u003eFingerboard Binding:\u003c\/strong\u003e None\u003cbr\u003e\u003cstrong\u003eHeadstock Shape:\u003c\/strong\u003e Solid with Square and Taper \u003cbr\u003e\u003cstrong\u003eHeadplate Material:\u003c\/strong\u003e East Indian Rosewood\u003cbr\u003e\u003cb\u003eHeadplate Logo Style:\u003c\/b\u003e Script Old Style Overlay\u003cbr\u003e\u003cb\u003eHeadplate Binding Material:\u003c\/b\u003e None\u003cbr\u003e\u003cstrong\u003eHeadplate Detail:\u003c\/strong\u003e None\u003cbr\u003e\u003cstrong\u003eTuning Machines:\u003c\/strong\u003e Nickel Open Gear\u003cbr\u003e\u003cstrong\u003eKnob:\u003c\/strong\u003e Butterbean\u003cbr\u003e\u003cstrong\u003eNut Material:\u003c\/strong\u003e Bone\u003cbr\u003e\u003cstrong\u003eCase:\u003c\/strong\u003e Hardshell\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Martin","offers":[{"title":"Default Title","offer_id":53221902680248,"sku":"10Y25SUPERD18","price":3399.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0888\/2795\/3336\/files\/Martin3067937_001availableatInterStellarGuitars.jpg?v=1780170781","url":"https:\/\/www.interstellarguitars.com\/products\/martin-super-d-18-acoustic-guitar-natural","provider":"Interstellar Guitars","version":"1.0","type":"link"}
