An electronic upright bass (10) produces sound closely approximating the sound produced by an acoustic upright bass. The bass includes a body (12) defining compartments (86, 88, 90) and slots (174, 176) placing the compartments in communication with the exterior of the body. The compartments and slots permit the bass to operate like the top table and portals of an acoustic upright bass. Piezoelectric transducers (64) are located beneath the feet of the bridge (44) and, thus, convert the authentic vibration of the body to electrical signals for reproduction through an amplifier and speakers. Magnetic pickups (36) mounted beneath the strings (24) of the instrument provide the component of the sound corresponding to the pure clean vibration of the strings. |
