Martin Super D-18 Standard Series Super D-14 Fret Acoustic Guitar with Hardshell Case – Aging Toner

The Martin Super D-18 takes the legendary Martin Style 18 Dreadnought to a new level with a larger Super D-14 Fret body, solid genuine mahogany back and sides, a spruce top with Aging Toner, and vintage-inspired Golden Era bracing. Designed for players who want powerful projection, deep bass, exceptional dynamic range, and the unmistakable Martin acoustic guitar sound, the Super D-18 delivers a bold voice while retaining the familiar character of a traditional Dreadnought.

With approximately 20% more internal air volume than a standard Dreadnought, the Super D body produces increased volume, thunderous low end, and impressive headroom. The spruce top provides clarity and projection, while genuine mahogany back and sides add warmth, punch, and focused midrange character.

The forward-shifted Golden Era scalloped X-bracing is inspired by Martin's vintage-focused designs and helps the Super D-18 respond quickly and dynamically across the entire frequency range. Whether you're flatpicking, strumming, accompanying vocals, performing on stage, or recording in the studio, this Martin acoustic guitar is built to deliver a powerful and expressive performance.

Classic Style 18 appointments—including black binding, abalone dot inlays, an ebony bridge and fingerboard, faux tortoise pickguard, and an Aging Toner top—give the Super D-18 a timeless appearance. The GE Modified Low Oval neck with High-Performance Taper provides a comfortable playing feel, while the 1 3/4-inch nut width offers ample room for both fingerstyle and flatpicking techniques.

The Martin Super D-18 is an excellent choice for serious acoustic guitar players looking for a premium USA-made Martin Dreadnought with increased projection, powerful bass response, traditional tonewoods, and modern playability.
