An acoustical device is provided in the form of a stringed musical instrument having a hollow resonant body. A speaker is coupled to the resonant body so that the speaker generally overlays the strings of the musical instrument. A power supply is mounted to the instrument for powering the speaker. A sound processing device is provided for receiving at least one of a first sound signal that is generated from the strings of the musical instrument and a second sound signal. The sound processing device generates an output signal to the speaker from at least one of the first and second sound signals. The sound processor has at least one non-overall-volume sound effect generating function.
