Abstract

See full text

The invention provides a stringed musical instrument comprising a guitar-type hollow body, a neck joined to the hollow body, and a banjo-type pot comprising a rim, a head and a tension hoop, positioned within a first interior chamber within the hollow body. The rim and head define a second interior chamber within the banjo-type pot. The banjo-type pot is affixed to a back surface of the hollow body such that the head of the banjo-type pot is proximal to a front surface of the hollow body and distal to the back surface of the hollow body. The banjo-type pot is positioned within the first interior chamber to form a path for sound waves generated by the head to travel from a second interior chamber within the banjo-type pot through the first interior chamber and out of at least one opening provided on the front surface of the hollow body.
