A tremolo clamp for attaching to a tremolo-equipped musical instrument having a tremolo arm and retaining the tremolo arm in a selected position. The tremolo clamp includes a clamp rod extending in a longitudinal direction, a fixed clamp arm fixedly attached to a first end of the clamp rod, a first positionable clamp arm slidingly attached along the clamp rod, and a second positionable clamp arm slidingly attached along the clamp rod. The first positionable clamp arm is arranged between the fixed clamp arm and the second positionable clamp arm.

A stringed musical instrument saddle containing a plurality of electrically independent transducers and associated electrical conditioning components where each transducer is located within the saddle such that it is sensitive to the vibratory energy of a corresponding string or course and senses the vibratory energy in both vertical and horizontal modes. The saddle contains at least one multi-conductor connector which connects to a removable multi-conductor cable to convey the transducer signals out of the saddle to external receiving electronics. The saddle is constructed of workable materials such that its top and bottom can be fit to a particular instrument by a technician.

A plastic ukulele has a sound board, a fretboard, a head plate and a lower half of the body integrated into a complete ukulele body. Attached to the bottom surface of the sound board are two paralleled outline reinforcing ribs which are in parallel with the outline of soundboard on the inside. The sound board has a sound hole in the upper middle part. Around the sound hole are two sets of lengthwise and widthwise paralleled reinforcing ribs. The part of sound board which is surrounded by the lower widthwise reinforcing ribs and the lower bout of outline reinforcing ribs is resonance section with a thickness of 1.0-1.4 mm only. Attached to the bottom surface of resonance section is a grid bracing structure in a one-piece molding with the sound board.

A fret leveling apparatus that is configured to provide leveling of frets on a fret board of a stringed instrument such as but not limited to a guitar. The present invention includes a body wherein the body in its preferred embodiment is rectangular in shape. The body includes a first end and a second end and further has an upper edge surface and a lower edge surface. The lower edge surface is operable to engage the frets during use of the present invention and has an adhesive material secured thereto. The body includes a first aperture and second aperture having a first height adjustment member and a second height adjustment member operably coupled therein. The first height adjustment member and second height adjustment member are constructed so as to provide calibrated incremental height adjustment of the body with respect to the fret board once placed thereon through rotational movement.

A fret press system can install one or more frets in grooves of a substrate with a press connected to a caul. The fret may be positioned atop the groove prior to contacting the fret with a caul by operating the press. The fret may initially be forced into the groove with the caul with a first pressure before an incorrect fret position in the groove is detected with a sensor connected to the press. The caul can then be adjusting to correct the sensed incorrect fret position and subsequently used to finish installing the fret in the groove prior to a position of the fret in the groove being confirmed with the sensor.

A file for use in forming a groove in a nut or bridge of a string musical instrument. The file includes a filing edge that is rounded to the same radius as the string to be fitted in the groove it forms in the nut and bridge. A spine or rib is formed along the upper edge of the file to provide stiffening and permitting the file to not bow or flex when being used.

A stringed instrument tailpiece includes an elongate body that is top/bottom and left/right symmetrical. Openings are formed at a bridge-end of the elongate body to engage a musical instrument's one or more strings. An opening at the gut-end of the elongate body is configured to engage a gut, which attaches to an instrument endpin.
