when I adjusted the potentiometers on the guitar for base, treble and volume, I seemed to be able to tune in an audio broadcast channel and got that signal out the speakers.
There are many instances of poorly shielded equipment picking up AM radio broadcasts, since all you need is a diode, inductor, capacitor and antenna to receive it (A.K.A crystal radio). Just wiring can create inductance and capacitance and a makeshift rectifier is pretty simple to inadvertently create as well. A long cable can form an antenna. -- Scott
