For decades, dynamic microphones have been sent with the voice coil attached with the principal of the microphone's transformer, and perhaps not recommended to surface (‘floating'). The microphone's case is usually connected to the cable guard, which is attached to the microphone amplifier's soil (see Rane's website for more discussion).
By and large, energetic microphones are very calm products consequently of the mix of transformer isolation and balanced, floating transmission lines all through, in addition to protected, humbucking coils.
Therefore why not instruments? Guitars are once plagued by noise. Humbucking pickups are merely a partial (though essential!) solution. Well-known alternative would be to float practicing the guitar collection to a healthy result, being a microphone. The same idea was printed this 2001 patent program like this Tedeschi Trucks Youtube?
