O Come All Ye Faithful Chords A guitar pickup is actually just like an energetic mike coil. For decades, active microphones have been wired with the voice coil attached to the primary of the microphone's transformer, and not recommended to floor (‘floating'). The microphone's event is typically linked to the wire guard, that is linked to the mike amplifier's ground (see Rane's internet site for more discussion).
By and big, powerful microphones are very quiet devices as a result of the mixture of transformer isolation and balanced, flying transmission lines for the duration of, in addition to protected, humbucking coils.
Therefore you will want to guitars? Guitars are notoriously affected by noise. Humbucking pickups are only an incomplete (though important!) solution. The obvious option would be to move your guitar collection to a healthy productivity, as being a microphone. An identical thought was published that 2001 patent software such as O Come All Ye Faithful Chords?
