Abstract: A standard electronic module for an electric stringed musical instrument is provided. The standard electronic module is mounted within the main body of the electric stringed musical instrument in a module cavity in the back of the electric stringed musical instrument. The standard electronic module comprises two printed circuit boards, a main printed circuit board and a connector circuit board, wherein the standard electronic module provides rapid exchange of the main printed circuit board without changing the wiring harness of the electric stringed musical instrument, which is directly connected to the connector printed circuit board.

Abstract: A bifilar pickup for an electrical stringed musical instrument is provided. The bifilar pickup comprises a single coil wherein the coil is formed with two closely spaced but electrically isolated parallel wound wires. A guitar in combination with the bifilar pickup is additionally provided.

Abstract: A footswitch controller for an electric stringed musical instrument is provided. In one embodiment, the footswitch controller comprises a foot pedal assembly, base assembly, bottom plate assembly, battery pocket assembly, and compound assembly. The footswitch controller does not directly alter the input sound, but upon activation by a user sends a signal to the digital signal processor within the electric stringed musical instrument to alter the sound.

Abstract: A method of adjusting the presentation of music is provided. In the method, a sequence of musical notes is presented by a first music presenting device. A critical beat indicator defining a time within the sequence of musical notes for a critical beat point is received. An isolation indicator defining a period for note isolation for the sequence of musical notes is received. A velocity coefficient is calculated by a processor for each note of the sequence of musical notes. The velocity coefficient is calculated as a function of the defined time and the defined period for note isolation. The sequence of musical notes is presented by a second music presenting device using the calculated velocity coefficient.

Abstract: A stringed musical instrument body with a front plate having an integral cavity defined by a tail end inner edge, a neck end inner edge, a bass side inner edge, and a treble side inner edge is provided. The cavity cooperates with a back plate to form a resonance chamber. A method for making the stringed musical instrument body is also presented. In many instances, the stringed musical instrument is a guitar.
