  • Electric guitar circuit control and switching module
    Patent number: 6781050
    Abstract: An interchangeable passive electric guitar circuit control and switching module is integrated into an existing guitar to dynamically alter the electronic relationship of the guitar's electric components (i.e. the existing pickups, volume and tone controls, at least one tonality select switch, and output jack) which are connected to the module through a wiring harness. Individual interchangeable modules connected through the wiring harness establish finite and discrete electronic relationships through the guitar's existing electric components to produce a plurality of selectable desired tonality sounds from a single guitar.
