Three Guitar Stands A guitar pickup is essentially much like a vibrant mike coil. For decades, powerful microphones have been wired with the voice coil attached to the principal of the microphone's transformer, and perhaps not referenced to ground (‘floating'). The microphone's event is usually connected to the wire shield, which will be connected to the mike amplifier's ground (see Rane's website for more discussion).
By and big, active microphones are very quiet devices consequently of the mix of transformer isolation and healthy, flying indication lines for the duration of, in addition to shielded, humbucking coils.
So why not guitars? Guitars are notoriously plagued by noise. Humbucking pickups are just a partial (though essential!) solution. The most obvious option is always to move your guitar collection to a balanced result, being a microphone. The same strategy was published this 2001 patent program such as Three Guitar Stands?
