The enhanced resonator for banjo, or similar types of musical instruments, increases the comfort of playing a resonator banjo as an open back banjo. In addition, the `open back` banjo sound quality is improved by allowing more sound to escape from the back and sides of the banjo. Furthermore, the enhanced resonator acts as a resonating chamber, increasing the sound quality in much the same way as the reflections of sound in a concert hall increase sound quality, increasing the reverberation and sustain of the sound. Another feature of the enhanced banjo resonator is the embodiment that allows the banjo player to easily and very quickly change the sound of the banjo from an open back banjo sound to a resonator banjo sound.
