Tom Petty Nyc A guitar collection is essentially much like a vibrant microphone coil. For many years, active microphones have already been wired with the voice coil mounted on the primary of the microphone's transformer, and not referenced to soil (‘floating'). The microphone's event is usually connected to the cable guard, which can be attached to the mike amplifier's surface (see Rane's site for more discussion).
By and big, active microphones are extremely calm units consequently of the mix of transformer solitude and healthy, flying transmission lines through the duration of, as well as guarded, humbucking coils.
Therefore why not guitars? Guitars are once plagued by noise. Humbucking pickups are merely a partial (though important!) solution. The obvious answer is to float practicing the guitar pickup to a healthy result, being a microphone. The same thought was printed this 2001 patent request like this Tom Petty Nyc?
