For decades, powerful microphones have now been wired with the style coil mounted on the primary of the microphone's transformer, and perhaps not called to surface (‘floating'). The microphone's situation is normally connected to the cable shield, which can be connected to the microphone amplifier's surface (see Rane's site for more discussion).
By and large, active microphones are very calm units consequently of the mixture of transformer isolation and balanced, floating indication lines all through, in addition to guarded, humbucking coils.
Therefore why not instruments? Instruments are notoriously affected by noise. Humbucking pickups are only an incomplete (though important!) solution. The obvious alternative would be to float practicing the guitar pickup to a healthy production, as being a microphone. A similar strategy was published that 2001 patent request like this Electrical Guitar Company Facebook?
