Abstract: The invention relates to an electrical stringed and fretted musical instrument which has at least two pick-ups and a bass boost filter means and a high boost filter means. The output of the instrument is a combination of the magnitude of the pick-ups and the magnitude of the filter means. In accordance with the invention, a single joystick control varies all of these magnitudes simultaneously so as to simultaneously vary the entire combination with a single control. In accordance with a further embodiment of the invention, a second joystick control will simultaneously control volume and panning between two speakers.
