Gibson Les Paul T A electric guitar collection is essentially just like a dynamic mike coil. For decades, energetic microphones have already been wired with the voice coil attached to the primary of the microphone's transformer, and not recommended to surface (‘floating'). The microphone's situation is typically connected to the cable shield, which can be connected to the microphone amplifier's soil (see Rane's site for more discussion).
By and big, vibrant microphones are very quiet units consequently of the mixture of transformer solitude and balanced, floating sign lines through the duration of, along with protected, humbucking coils.
Therefore why not guitars? Instruments are notoriously affected by noise. Humbucking pickups are merely an incomplete (though essential!) solution. The obvious solution would be to move practicing the guitar pickup to a balanced result, just like a microphone. An identical idea was printed that 2001 patent application such as Gibson Les Paul T?
