Peak pre-war D-18 production. Scalloped bracing, Adirondack spruce, mahogany. The dreadnought was becoming the dominant acoustic guitar body style. These guitars would define the sound of American country and folk music.

Collector's Notes

Late 1930s D-18s are the most available pre-war examples. Still scalloped bracing and fully pre-war specs. Excellent value compared to same-era D-28s — typically 40-50% less.
