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.

An adjustable bridge unit for use with a stringed instrument, such as an electric guitar. The construction of the unit allows for an unimpeded string path from the rear of an adjustable height bridge in a downward trajectory toward a tailpiece. Moreover, the bridge unit may be used to perform a variety of corrective measures, such as saddle height, intonation, and string alignment.

This invention is an apparatus for straightening a guitar bridge or guitar bridge assembly comprising a U-shaped receptacle with a bottom, a first face and a second face; an adjustable drive on the first face that places force on the bridge; and at least two opposing braces on the second face, and wherein the second face is grooved to create a space between the receptacle and the bridge, and wherein the first and second face contain a sight line and the apparatus contains an adjustable drive which is capable of being turned by a hex wrench so that the force of the adjustable drive on one side and the two opposing braces change the shape of the bridge to a desired shape. The invention is also related to a method for straightening a guitar bridge.

The Stabilizer Tuner adjustably supports a formed spring or a pre-loaded coil spring element operable to hold a variable force of tension to enforce initial position. The Tremolo Stabilizer includes a thumbwheel arrangement to variably adjust the position of an independent stabilizer arrangement. Tremolo Spring Tuner includes a pre-loaded coil spring element or formed flat spring operable to exert a first variable force of tension to contact the body with the capacity to variably support the pivoting of tremolo under the variable force of the string tension; the first force of tension is essentially equal to the force of tension provided by the strings to establish the fulcrum tremolo at initial position.
