For many years, powerful microphones have been sent with the voice coil mounted on the primary of the microphone's transformer, and maybe not referenced to floor (‘floating'). The microphone's situation is typically linked to the wire shield, which is connected to the microphone amplifier's ground (see Rane's site for more discussion).
By and large, powerful microphones are extremely quiet products consequently of the combination of transformer isolation and healthy, hanging transmission lines for the duration of, as well as shielded, humbucking coils.
Therefore you will want to instruments? Instruments are notoriously overwhelmed by noise. Humbucking pickups are just a partial (though important!) solution. Well-known solution would be to float the guitar pickup to a balanced production, as being a microphone. The same idea was published that 2001 patent program like this Justin Hayward Youtube?
