Abstract: An electronic device which, when connected to an electric guitar, or other similar stringed instrument, will effect wireless transmission over a selectable frequency of the FM broadcast band. The unit is compact as it uses the metal strings of the guitar as a partial antenna. The unit remains stationary after being plugged into the guitar's input receptacle, and no transmitting portion of the device has to be attached to the musician's belt or guitar strap, or to the musician's person in any fashion. Furthermore, no large unsightly, cumbersome antenna extends from the device intself. The device is automatically turned on when plugged in.
