I Can Sing A Song A electric guitar pickup is basically much like an energetic mike coil. For many years, energetic microphones have now been wired with the voice coil mounted on the primary of the microphone's transformer, and maybe not called to floor (‘floating'). The microphone's event is normally linked to the cable guard, that is attached to the mike amplifier's floor (see Rane's website for more discussion).
By and big, powerful microphones are extremely quiet products as a result of the mix of transformer solitude and healthy, floating indication lines all through, in addition to shielded, humbucking coils.
Therefore why don't you instruments? Guitars are notoriously affected by noise. Humbucking pickups are merely a partial (though crucial!) solution. The most obvious solution is always to float the guitar collection to a healthy result, being a microphone. The same thought was printed that 2001 patent request like this I Can Sing A Song?
