The Dirty 30s Series 7 is a single 0 with a sound that will impress you. Chalk it up to our super clean Cross Lap bracing and top quality materials, the Series 7 packs a punch. The spruce top provides the foundation for classic acoustic tone beneath the Tobacco Sunburst finish. The bound soundhole and Harmonella stencil fretboard markers are both functional and stylistic. The Series 7 has a bone nut and saddle for excellent sustain, and ivory-button tuning machines for traditional mojo.
