Description

The D-18 (2025) is Martin & Co.'s Dreadnought acoustic guitar from the "Standard" series, featuring a Spruce top, Mahogany back and sides, a selected Hardwood neck, and an Ebony fingerboard. It is characterized by GE-Scalloped bracing, which provides greater brilliance and sound projection, a further lowered GE Modified Low Oval neck profile, a more rounded heel, neck, and bridge for increased comfort, and Ebony bridge pins. It has a nut width of 44.45 mm, a scale length of 645 mm, and a gloss finish on the top, back, and sides.

Overview of the D-18 (2025) by Martin & Co.

Understated looks, timeless sound. The warm tone of mahogany and spruce meets the performance of GE-scalloped bracing under the body, for an authentic, authoritative, and clear sound. Vintage details include open-gear tuners and classic 18-style trim, combined with a modern, low-profile neck for a sound rich in character.
One of the main novelties of the 2025 Standard series is the use of Golden Era (GE) Sitka spruce bracing for the top, a detail also present in the Modern Deluxe series, which gives a more vintage and airy tone, with enhanced sustain. The neck with a modified "Low Oval" GE profile retains the classic shape but has been optimized to offer a vintage appeal. The fingerboard has been thinned and features rounded edges for greater comfort, while the string spacing at the nut has been perfected. The new GE "modern belly" bridge features softer, more comfortable angles. Standard Series guitars are now equipped with bone or ebony bridge pins, depending on the model. Among the aesthetic updates, we find the elongated neck diamond, the angled nut, and a more articulate, vintage-style heel.
