The Martin Super D-18 takes the legendary Style 18 Dreadnought to the next level. With 20% more internal air volume than a standard Dreadnought, this Super D body delivers thundero us bass, increased volume, and extended dynamic range—all while keeping the iconic silhouette intact. Solid genuine mahogany back and sides add warmth and punch, while the spruce top ensures clarity and projection. Forward-shifted Golden Era scalloped X-bracing, as featured on the Modern Deluxe Series, makes every note responsive and powerful. Appointments like black binding, abalone dot inlays, and a satin-finished neck keep the look classic and the playability smooth. Paired with an ebony bridge and fingerboard, the Super D-18 is a bold evolution of an acoustic icon—built for players who want to be heard.SpecificationsHighlightsSuper D-14 Fret body sizeGenuine Mahogany back and sidesSpruce top with Aging Toner top colorGE Modified Low Oval with High-Performance Taper neck1 3/4'' fingerboard width at nutMolded Hardshell caseRecommended Strings: Authentic Acoustic Lifespan® 2.0 Guitar Strings Phosphor Bronze - MediumTopTop Material: SpruceFinish Top: GlossTop Color: Aging TonerTop Inlay Material: Multi-StripeTop Detail: NoneBinding: BlackBridge Material: EbonyBridge Style: GE Modern Belly - Drop in SaddleBridge String Spacing: 2 5/32"Bridge Pin Material: EbonyBridge Pin Dots: NonePickguard: Faux TortoisePickguard Inlay: NoneRosette: Old Style 18 Multi-StripeSaddle: BoneSaddle Radius: 16"BodyBody Size: Super D-14 FretConstruction: Dovetail Neck JointBack Material: Genuine MahoganySide Material: Genuine MahoganyBack and Side Finish: GlossBack and Sides Color: Dark MahoganyBack Detail: NoneSide Detail: NoneBack Purfling/Strip: Style 18Back Inlay Material: NoneSide Inlay Material: NoneBracing Pattern: Forward Shifted X BraceBrace Shape: GE-ScallopedBrace Material: SpruceBrace Size: 5/16"Heelcap: BlackEndpiece: BlackEndpiece Inlay: NoneNeckNeck Shape: GE Modified Low OvalNeck Taper: High-Performance TaperNeck Material: Select HardwoodNeck Color: Dark MahoganyFinish Neck: SatinScale Length: 25.4"Number of Frets Total: 20Neck Joins Body At: 14th FretFingerboard Material: EbonyFingerboard Width at 12th Fret: 2 1/8''Fingerboard Width at Nut: 1 3/4''Fingerboard Inlay Style: Old Style 18Fingerboard Inlay Material: AbaloneFingerboard Binding Material: NoneSide Dots: WhiteHeadstockHeadstock Shape: Solid with Square TaperHeadplate Material: East Indian RosewoodHeadplate Logo Style: Script Old Style OverlayHeadplate Binding Material: NoneTuning Machines: Nickel Open GearKnob: ButterbeanNut Material: BoneMiscCase: Molded HardshellLabel: NoneElectronics: NoLeft Handed Availability: truePleked: true Show more
