Grote Brand Electric Guitar Semi Hollow A guitar pickup is actually similar to an energetic mike coil. For many years, vibrant microphones have now been sent with the voice coil mounted on the principal of the microphone's transformer, and maybe not called to surface (‘floating'). The microphone's situation is usually connected to the cable shield, which is connected to the mike amplifier's floor (see Rane's site for more discussion).

The most obvious alternative is to float the guitar pickup to a balanced productivity, being a microphone.
