Price includes Martin molded case. Martin Standard Series Martin launched this much imitated "Standard Series" line nearly a century ago and set the standard for all modern acoustic guitars—starting with the Dreadnought, a shape that Martin first built in 1916 to provide a bigger, richer guitar sound at a time when there was no amplification, for the accompaniment of singers in larger settings, including auditoriums. These instruments constitute the historic core of the Martin line and represent the majority of sizes and styles that have evolved during this century. The Standard Series models are known for resonant warmth of tone with tastefully restrained styling. For the most part, Martin is credited with inventing these styles and shapes, and guitar makers in general have moved to adopt Martin's size designations as the standard for the industry. Standard features for the Standard Series generally include solid wood top, back, and sides, polished gloss finish, and a hand-fit dovetail neck attachment.
