Abstract: Methods and apparatus for providing a high performance stringed instrument. In one embodiment, the stringed instrument comprises an electric guitar constructed entirely of sheet metal, with the body and neck permanently joined together to produce a one piece (unitary) style guitar construction. This method of construction results in improved overall consistency of the product. In particular, the construction utilizes a substantially homogenous material throughout the guitar and further includes a stronger, stiffer and straighter neck that allows for a more consistent sound than is possible using traditional manufacturing materials such as wood. Such a construction also offers improved sustain of string vibration, an attribute that is highly desirable to guitar players. The incorporation of a unique supporting structure into the headstock contributes to a unique warm timbre when played that has heretofore been unachievable in combination with improved sustain characteristics.

Abstract: A support is configured to support and apply a constant or near-constant tension onto a wire or string, such as a musical string of a stringed musical instrument. The wire is attached to a carrier that moves axially. One or more springs operate between the carrier and a point that is fixed relative to the carrier and apply a transverse spring force to the carrier. A spring angle is defined between a line normal to the axis and a line of action of each spring. The transverse spring force can have an axial force component and an axial spring rate that is a function of the spring angle. The carrier can be positioned so that the axial spring rate is zero, negative or positive. A primary spring can apply a primary force directed coaxial with the wire. If the wire changes in length the primary force will correspondingly change, as will the axial force component.

Abstract: A device for producing percussive sounds while simultaneously playing a plucked stringed instrument such as a guitar is disclosed. A plate attached to the front panel of a guitar contains a pivoting arm assembly. The arm is placed below the guitar strings such that it enables the player's hand to strike the swinging arm at the completion of a strumming downstroke on the strings. This causes the arm to swing down causing the actuation of an electric switch which then actuates the transmission of a signal for playing the percussive sound. This may be accomplished within less than 0.01 seconds; therefore, the resulting percussive sound virtually coincides with striking of the swinging arm. The swinging arm is attached to the plate with a spring loaded mechanism in a way that the arm rebounds to its original position following the swing-down making the arm ready for the next hand strike.

Abstract: An accessory for attachment to a stringed musical instrument that mechanically limits depth of picking action by providing interference to the finger, fingernail, or pick. A plate or “anvil” either flexible or rigid, is adjustably positioned beneath the strings to intercept and arrest a picking element. In a first embodiment, picking depth is roughly controlled my manually forcing the anvil up and down on a flanged support post. In a second embodiment, picking depth may be finely controlled by a knurled thumbwheel or similar mechanism on the anvil support posts. The flexibility of the plate provides a shock absorber, thereby creating a realistic feel to the player. The flexible plate assures both limitation of depth of picking action, and also renders picking action consistent as to depth.

Abstract: A guitar comprising a sound box that comprises an upper sound board having a sound hole, a lower sound board, a resonator plate comprising a relatively thin sturdy material exhibiting a vibrational springy characteristic, with the resonator plate supporting a bridge, and a resonator conductor positioned between the upper and lower sound boards for transmitting vibrations directly from the resonator plate to the lower sound board and to create additional air vibrations within the sound box.

Abstract: This invention applies to a bolt-on neck guitar or similar instrument or device. The mechanism of this invention, a multiple section hinge with one end flap attached to the neck and the other end flap attached to the body while the center section stays sandwiched between the neck and the body in normal use, allows the removal of the neck screws with the strings under tension by the hinge absorbing the horizontal stress produced by the tension of the strings. The neck is then rotated 180 degrees to rest on top of the body where it can be secured with a clamp or a strap for transportation or stowage. The neck holding screws can be replaced with a large single one, reducing the time required to loosen the neck, while still maintaining the possibility of using the normal four screws in addition to or in lieu of the single one if so desired, since the tone of the guitar is improved when the pressure of the neck-body junction is increased and distributed over a larger area.
