    摘要： A pitch adjustment device for selectively adjusting the pitch of multiple strings of a stringed musical instrument from the open pitch (normal unadjusted pitch) while playing using a single lever, wherein the tension and pitch of different strings can be adjusted by different and adjustable amounts for each adjustable string. The device comprises a support frame configured to be mounted onto the stringed musical instrument and a string puller rotatably coupled to the support frame and rotatable about a first axis. At least two pitch adjusters are attached to the string puller. Each pitch adjuster has a string support for securing a respective adjustable string and is adjustable to adjust the respective string support to a plurality of different radial positions from the first axis. A lever coupled is the string puller such that pivoting the lever rotates the string puller relative to the frame about the first axis.

    摘要： A pitch adjustment device for selectively adjusting the pitch of the string(s) of a stringed musical instrument. Each string of the instrument is attached to a respective pitch adjustment device. Each pitch adjustment device comprises a tuning key to which the string is attached. The tuning key is mounted on a pivotable lever. A pull rod is attached to the lever to selectively pivot the lever. When the pull rod is actuated, it causes the lever and the tuning key to pivot, thereby adjusting the tension or pitch of the string. While the lever and tuning key pivot, the adjustment of the tuning key relative to the lever remains unchanged. Accordingly, when the pull rod is de-actuated, the lever and tuning key return to their original position and the string returns to its normal open pitch. A roller nut having a pivoting knife-edged surface is also provided.

    摘要： A pitch adjustment device for selectively adjusting the pitch of at least one of a plurality of strings on a stringed musical instrument. The device comprises a support frame configured to be mounted onto the stringed musical instrument. A string puller is rotatably coupled to the support frame. A string support is coupled to the string puller. The string support is adjustably positionable along the string puller to selectively position the string support on the string puller in alignment with each of the strings one at a time. The string support also has a string retainer for securing a string. A lever is coupled to the string puller such that pivoting the lever rotates the string puller and the string support relative to the frame about the first axis. The lever has a normal position and an actuated position in which the lever is pivoted to adjust the pitch.

    摘要： A connector, and a connector system that implements the connector, that exhibits a value of characteristic impedance that is responsive to a tuning insulator. In one embodiment, the connector includes a connector body that defines a longitudinal axis, and a conductor that is disposed in the connector body so that it is aligned coaxially with the longitudinal axis. The connector also includes a tuning insulator that has a pre-determined effect so that, when the insulator is positioned on a portion of the conductor, the value of characteristic impedance of the connector changes from a first value to a second value.

    摘要： A pitch adjustment device for selectively adjusting the pitch of the string(s) of a stringed musical instrument. Each string of the instrument is attached to a respective pitch adjustment device. Each pitch adjustment device comprises a pivotable string puller wherein pivoting of the string puller adjusts the pitch on the string. The string puller is pivotably mounted on a puller pivot and has a string support surface upon which the string rests, wherein pivoting of the string puller about an axis adjusts the pitch on the string. A pivoting link is pivotably coupled to the string puller. A plurality of pull rods and levers are operably coupled to the pivoting link and actuators are coupled to the pull rods for causing the pivoting link to pivot thereby causing the string puller to pivot and adjust the pitch of the string.
