A portable speaker system for an electric string instrument such as a guitar. The portable speaker system has a housing including an audio jack for receiving a raw audio signal from a guitar, an amplifier, a speaker, and a power supply. The portable speaker system attaches to the guitar by a button connector which releasably attaches to a strap button of the guitar, and a stabilizer for inhibiting rotation of the portable speaker system when attached to the guitar. The portable speaker system portably generates output sound from the raw audio signal. The portable speaker system can couple with a portable computing device, which can process the raw audio signal and provide a supplementary audio signal, from which the portable speaker system can portably generate output sound.

Sonic improvement for all stringed instruments that employ a fulcrum tremolo bridge system with back of instrument counter tensioning springs. The improvement is provided by securing springs to claw assembly, as well as securing claw assemble to a flat plate of material which is in turn secured to instrument body. The claw and resonator plate can be fabricated as two individual pieces then fastened together or as a combined one piece assemble that is then fastened to instrument body.

Provided is a modular string instrument including a core string instrument and interchangeable instrument body types. The core including: a core shell forming a basic shape of the core string instrument, a string instrument head, a neck base, a chassis assembly configured to be inserted into the core shell, extending from the head to the neck base and comprising a strings anchoring bridge, a plastic fret board configured to have frets attached thereon, the fret board configured to cover the core shell and to encase the chassis assembly within the core shell, a neck base cover configured to be attached to the neck base, a pickup cassette bay configured to encase an interchangeable pickup cassette, and strings stretched from the bridge over the pickup cassette bay, over the neck base to the head.

A programmable signal processing and musical instrument setup system for stringed musical instruments, comprising at least one analog signal processing circuit, a control circuit operably coupled to at least one analog signal processing circuit, and a storage unit operably coupled to the control circuit, being arranged on the musical instrument for storing setup parameters for the musical instrument. The system comprises: a communication module with an individual identification information connected to the control circuit for enabling communication with an external programming device that has a storage unit configured for storing an individual identification information of at least one musical instrument, in association with the musical instrument in at least one configuration file. The external programming device is further configured for receiving and sending data to and from a selected musical instrument, when connected, wherein the data transferred to the musical instrument can be stored in the musical instrument and can be used after the external programming device is disconnected.

The magnetic pickup positioning mechanism for electric musical instruments is mounted beneath the strings between the neck and bridge of an electric musical instrument like the electric guitar or bass. It includes a length of “C” profile track fastened to the guitar and one or more slide-swivel assemblies that twist-lock into, slide and rotate along the track. Magnetic pickups are mounted to the slide-swivel assemblies that allows the player to use their hand to slide and rotate the pickups to various positions and angles between the neck and bridge in order to get a wide variety of tones.

The present invention relates to a mixer apparatus (30) for mixing audio signals from a musical instrument (10). The mixer apparatus (30) comprises plural input circuits (34) and an audio signal mixer (36). Each of the plural input circuits (34) has an audio signal input which, in use, is coupled electrically with and thereby receives an audio signal from a different one of plural musical instrument pickups (32) comprised in the musical instrument. The audio signal mixer (36) receives audio signals from the plural input circuits (34) and mixes the received audio signals with one another. Each of the plural input circuits (34) comprises a linear active circuit in an audio signal path between the audio signal input and the audio signal mixer (36).

An electric guitar comprising a rotatable disc positioned underneath the guitar strings and comprising a plurality of attachment points; at least one pic comprising a body configured to be received by an attachment point of the rotatable disc and a flexible wire member extending from the body away from the rotatable disc; drive means configured to rotate the rotatable disc relative to the guitar body such that each time the at least one pic passes the at least one string it engages therewith causing the at least one string to vibrate and the at least one pickup generates an electrical signal; and an output jack for outputting the electrical signal to an amplifier.

Wirelessly programmed and controlled switching system for use with stringed musical instruments (e.g., guitars) to enable a user to seamlessly change pickup coil settings without having to adjust the physical connections between the switch and the pickups.

A percussion instrument motion reproduction device includes a percussion instrument. The percussion instrument includes a vibration portion. The percussion instrument motion reproduction device includes a first driving portion. The first driving portion of the percussion instrument motion reproduction device is configured to visually displace the vibration portion in response to an electrical signal.
