For decades, energetic microphones have now been sent with the voice coil attached with the principal of the microphone's transformer, and maybe not introduced to floor (‘floating'). The microphone's situation is typically linked to the cable shield, that will be attached to the microphone amplifier's surface (see Rane's site for more discussion).
By and big, dynamic microphones are extremely calm products consequently of the mix of transformer isolation and healthy, hanging sign lines all through, as well as shielded, humbucking coils.
So why don't you instruments? Instruments are notoriously plagued by noise. Humbucking pickups are only a partial (though crucial!) solution. The most obvious solution is to float the guitar collection to a healthy output, just like a microphone. A similar thought was published that 2001 patent software such as Musicans Friend Kansas City?
