Electric Guitar Wavetable A guitar pickup is essentially just like a vibrant mike coil. For decades, dynamic microphones have already been sent with the voice coil attached with the primary of the microphone's transformer, and maybe not introduced to surface (‘floating'). The microphone's event is typically linked to the wire shield, which can be linked to the microphone amplifier's soil (see Rane's site for more discussion).
By and large, dynamic microphones are extremely calm devices consequently of the mix of transformer isolation and balanced, floating sign lines through the duration of, as well as protected, humbucking coils.
Therefore why don't you instruments? Instruments are notoriously affected by noise. Humbucking pickups are only an incomplete (though essential!) solution. Well-known answer would be to float practicing the guitar pickup to a healthy result, being a microphone. An identical strategy was published this 2001 patent software such as Electric Guitar Wavetable?
