Medford Guitar Center A guitar pickup is actually similar to an energetic microphone coil. For many years, energetic microphones have already been wired with the style coil mounted on the primary of the microphone's transformer, and perhaps not called to floor (‘floating'). The microphone's event is typically connected to the cable guard, which is connected to the microphone amplifier's floor (see Rane's website for more discussion).
By and large, powerful microphones are very quiet devices as a result of the mixture of transformer isolation and balanced, flying transmission lines for the duration of, along with guarded, humbucking coils.
Therefore why not guitars? Instruments are once plagued by noise. Humbucking pickups are only a partial (though crucial!) solution. The most obvious alternative would be to float your guitar pickup to a healthy production, as being a microphone. The same thought was printed this 2001 patent software like this Medford Guitar Center?
