Abstract: A bracket for mounting a tuning device on a headstock of a string instrument and a bracket-mountable tuning device are disclosed. A primary arm with a plate attaches to a spring arm with a clamping arm by a releasable ratchet engagement. The clamping arm is reciprocable to the plate. A tuner attaches in a rotatable engagement to the plate opposite a mounting surface. An instrument headstock can be positioned between the plate mounting surface and clamping arm and the clamping arm moved toward the plate to a clamping position with the headstock trapped therebetween with substantially constant pressure on the headstock. The tuner is substantially hidden from the front view of the headstock. The clamping arm is maintained in the clamping position by the ratchet engagement until the ratchet engagement is released.

Abstract: A stringed musical instrument, such as a guitar, which includes a bridge which does not stress the top of the guitar either vertically or laterally. Vertical and lateral forces due to string tension are balanced out within the bridge assembly. Also disclosed is an adjustable height tailpiece and means for adjusting the intonation of the instrument by adjusting the distance that the neck projects out of the body.

Abstract: An electric stringed musical instrument of the lute family, and in particular, a double bass, wherein the body, neck, and headstock are cut out of a single laminated section of a cone. The front surface of the headstock is coplanar with the neck and body, and the back surface is substantially concentric with the front surface. The strings are anchored in a central cutout in the headstock. Also disclosed is a neck-straightening truss rod capable of exerting either compressive or tensile forces on the neck, a pair of sensors sensitive to string vibrations coupled the bridge which are summed and differenced to provide signals useful in connection with plucked and bowed strings respectively, and a twist resisting support to make a slim double bass practical.

Abstract: A screw stabilizer for selectively adjusting a first element with respect to a second element. The screw stabilizer includes a screw having a first end adapted to be supported on the first element and a second threaded end to be adapted to be threaded to the second element. First and second opposing washers are supported on the first end of the screw. The first washer includes a plurality of radially extending detents on the inner surface thereof. A plurality of ball bearings are sandwiched intermediate the first and second washers. The first end of the screw presses the first and second washers towards one another. The ball bearings selectively ride in the detents to selectively, releasably lock the screw in a desired position.
