An acoustic bass guitar includes a lower body, a neck extending upwardly from the lower body, and a headstock disposed on an upper end of the neck. The lower body includes a bridge and saddle to support the strings, which are affixed at opposing ends to tuners on the headstock. An upper body that is continuous with the lower body includes a curved extension that extends outwardly from an upper side of the lower body. The upper body curves inwardly toward the upper end of the neck, connecting to the headstock and defining an open area between the neck and the inner sidewall of the upper body. One or more sound holes are disposed on the front face and outer sidewall of the upper body. A retractable stand allows the device to be played in horizontal or vertical orientations. The curved upper body adds neck stability, sound and sustain.
