Abstract: A low-friction bridge for a stringed musical instrument employs a roller saddle that is adapted and positioned to roll upon a race. The race includes structure to guide the roller saddle as it rolls. A musical string is seated in a circumferential groove/saddle formed in the roller saddle. As the musical string stretches or contracts the saddle rolls, and thus the musical string does not slide in the saddle. As such sliding friction is avoided in favor of rolling friction of the roller saddle rolling upon the race. One or more contact members can be biased into contact with side faces of the roller saddle.

Abstract: A musical instrument, particularly a stringed instrument, has a structure that decouples the body of the player from all parts of the instrument which are indirectly responsible for the sound production for preventing the body of the player from damping the vibrations of the instrument. Instead of a top cover being the main source of indirect sound production, the musical instrument now has an annular plate which is positioned between covers. Any damping effect on the resonance of the annular plate is minimized by positioning a bridge on the annular plate to avoid any contact between the bridge and the top cover, and applying an acoustically decoupling layer between the covers and the annular plate. The covers provide protection against any damping effect of the player's body on the annular plate. This structure also minimizes the tendency of an acoustic feedback loop,2 which may occur in the case of an electrically amplified stringed instrument.

Abstract: The present invention is a bridge truss that alleviates tensile and compressive stresses applied to an acoustic stringed instruments soundboard from the bridge. These tensile and compressive stresses are transferred through the bridge truss to chamber of the acoustic stringed instrument instead. The bridge truss allows the support brace of the acoustic stringed instrument to be reduced or eliminated. The bridge truss provides the soundboard with the ability to produce longer sustained vibrations, and vibrations of greater amplitude—increasing performance and tone. Also, the relative height of the soundboard can be altered for greater playability, at a user's discretion. A user only needs to reposition threaded adjustment rods from atop the bridge of the acoustic stringed instrument in order to transfer more or less stress to the bridge truss.

Abstract: For over 150 years, conventional acoustic guitar designs have anchored the strings on a bridge attached to the guitar face; passing over a saddle; notched to align the strings over the fingerboard; and terminating at the tuning keys. The strain on the bridge and entire guitar face top over time eventually causes the thin guitar face top to warp. This phenomenon negatively impacts the quality of the instrument. The current patent, a bridge for stringed instruments (No. 6372971) was designed to eliminate surface warping to the guitar face of the instrument by distributing the load from the strings transversely across the guitar face. The principle of this feature, added to the current aforementioned patent, allows the user to raise and/or lower the strings (for the ease and comfort of the user) relative to the fingerboard without affecting the tuned strings or requiring a major operation to modify the saddle.

Abstract: A stringed instrument, for example an electric guitar, is arranged to produce a tremolo effect by providing the tailpiece with a number of saddles corresponding to the number of strings, each saddle having a slot for anchoring its string. The tailpiece is pivotable about an axis substantially perpendicular to the strings in order to change the tension in the strings to produce the desired tremolo effect. The tailpiece includes a housing in which the saddles are provided with a screw adjustment which varies the off-set of the saddle from the axis of the pivot. The greater the off-set of the saddle from the pivot, the greater the extension or release of the string on activation of the tremolo lever to turn the tailpiece. Thus, the position of the saddles relative to each other can be made so that on activation of the lever which pivots the tailpiece, the strings whose tension is changed remain in harmony.

Abstract: This invention improves guitar pitch stability and requires no modifications to a guitar or any of its parts. It is a low profile design which pertains in particular to Fender Stratocasters or any electric guitars with a similar bridge plate and tone block design. This invention does basically two things. First, the guitar strings are rerouted giving a much softer string bend past the string saddles (similar to Gibson guitars) which significantly reduces string drag (friction) at the saddles. After “dive-bombing” downward or going upward in pitch via the tremolo arm (as with a Stratocaster), the guitar returns to its original pitch when the tremolo arm is released. Second, readjustable saddle clamps are used which hold and lock all six string saddles together in position and to the bridge plate after string height and intonation adjustments have been made.

Abstract: Pyrocarbon components have been found to create richer, clearer sound when employed as bridges (19), saddles (1), nuts (2), frets (3), tuning heads (4), pegs (9) and other components which contact the strings in guitars (6, 16), violins (11) and like stringed musical instruments. Bridges/saddles and nuts of stringed instruments produce a marked difference in the sound when pyrocarbon components are used compared with currently used materials. There is a significant increase in sound volume for a given intensity of string movement, along with richer harmonics and a clearer, less muddy sound. The crystalline structure of pyrolytic carbon minimizes the damping of string vibration as it is transferred to the sound-amplifying portion of acoustic instruments, producing a rich, pleasing and higher volume sound. The useful life of strings is increased in contact with pyrolytic carbon components before they go “dead” or break.

Abstract: An aspect of the system relates to an intonation control mechanism for controlling, for example, the pitch of a plucked or vibrated string of a stringed instrument through a string contact point located at an appropriate intonation harmonic.
