A pitch changer system for a string musical instrument, including a lever assembly, a rotating saddle assembly, a swing plate, and a lever tensioning assembly. Applying force to move the lever in a first direction forces a bell crank matingly coupled to the lever into rotation such that a coupling system of the lever tensioning assembly causes the swing plate to force a rotating saddle of the rotating saddle assembly into rotation to elongate and thereby temporarily change the pitch of a string coupled to the rotating saddle.

The retainer for securing a musical instrument string to a body of a musical instrument includes a first casing portion defining a first opening and a ball-end chamber therein. The first opening is located at a proximal end of the retainer and a second casing portion is located at a distal end of the first casing portion. The second casing portion defines a passageway from the ball-end chamber to a second opening located at a distal end of the retainer. The passageway length is greater than the ball-end chamber length, and the ball-end chamber width is greater the passageway width.

A foldable stringed instrument having a neck and/or body that may assume a reduced profile by folding an upper neck portion away from the playing position through the use of a translating bridge assembly and a translating truss assembly, wherein the foldable stringed instrument is capable of housing or otherwise being coupled to any of a variety of electronics or electrical components (e.g. a smart phone or tablet computer) having one or more applications (apps) for driving the operation, functionality and/or effects associated with the foldable stringed instrument.

Disclosed is a locking nut assembly that includes a baseplate mounted on the head of a musical instrument, such as a guitar. The baseplate includes channels configured to receive strings of the musical instrument and at least one locking plate to secure the strings in the channels. A bracket couples a truss rod positioned in a neck of the musical instrument to the baseplate.

A three-piece modular stringed instrument comprising a body module, a neck module, and a tremolo module with expedited assembling and disassembling steps enabled by the design of a tremolo system to expand its use of the pivotal string tension control in synergistic combination with an additional leveraging string tension control at the neck end of the strings, as well as a streamlined neck joint system comprising an oversized neck pocket, a self-adjusting axial coupling, and an adjustably static side-to-side neck clamping structure. The saddle design of the tremolo system comprises the generic machine tuners for conventional electric guitar instruments on a modular headless guitar format with conversion functionality between a full tremolo-enabled configuration and a hardtail configuration.
