Brendon Small Snow Falcon A electric guitar pickup is essentially similar to a powerful mike coil. For many years, vibrant microphones have been wired with the voice coil attached to the principal of the microphone's transformer, and not introduced to ground (‘floating'). The microphone's case is typically linked to the wire guard, that will be connected to the microphone amplifier's soil (see Rane's website for more discussion).
By and big, powerful microphones are extremely quiet products consequently of the mix of transformer isolation and balanced, floating indication lines during, along with shielded, humbucking coils.
So why don't you guitars? Instruments are notoriously plagued by noise. Humbucking pickups are merely a partial (though important!) solution. Well-known alternative is to move practicing the guitar collection to a healthy production, as being a microphone. A similar thought was published that 2001 patent application like this Brendon Small Snow Falcon?
