Abstract: A string-bridge interface system includes a plurality of string-bridge interface units to provide coupling between strings of a musical instrument and one or more sound bridges of the musical instrument, which are further coupled to the sound board of the musical instrument. Such coupling provided by the string-bridge interface units allows for reduced loading of the sound board and more direct routing of the strings.

Abstract: A detachable and portable top pickup for a musical stringed instrument, comprising a clamp having an open end for attaching a top pickup on a pickup holder to a section of a guitar and a connector coupling the top pickup to an elongated bar, the connector allowing the top pickup to slide along the length of the elongated bar. A second clamp can be used to attach to another section of the guitar to get a stronger and more balanced hold for the top pickup. The clamps allow the top pickup to be removed, transferred or reinstalled without causing any damage on the surface of the guitar.

Abstract: The string securing apparatus for string instrument of this invention arranges a plurality of saddle-attaching members on the top face of a bridge base in correspondence with strings, and secures them to the bridge base so that they can be movably adjusted in the front-rear direction. A bridge saddle is attached to each saddle-attaching member so as to rotate up and down. The string is inserted through a pipe section in the bridge saddles and led above the bridge saddles by a lever attachment hole; the string is curved forward to a string supporting section. A cam lever is inserted in the lever attachment hole of the bridge saddles so as to freely rotate, and a spring presses the cam lever forward. A cam section of the cam lever pushes the string and secures it by tightening it to the string supporting section.

Abstract: A stringed instrument, such as a guitar, is provided. The instrument includes a body, a fretboard mounted on the body, a bridge having a plurality of bridge critical contact surfaces mounted at one side of the fretboard, a nut mounted on the body at an opposing side of the fretboard, and a plurality of strings. Each of the strings has a first end and a second end and a predetermined length extending between the first and second ends. The strings are arranged in contact with corresponding bridge critical contact surfaces and the nut, and are arranged to extend across the contact surfaces. Each of the strings is anchored at a location wherein the first end is spaced from a corresponding bridge critical contact surface by no greater than approximately one inch and the second end is spaced from the nut by no greater than approximately one inch.
