Fender Standard Stratocaster Used A electric guitar pickup is actually similar to a vibrant microphone coil. For decades, dynamic microphones have been sent with the voice coil mounted on the principal of the microphone's transformer, and perhaps not referenced to ground (‘floating'). The microphone's situation is typically linked to the wire shield, which will be linked to the mike amplifier's ground (see Rane's site for more discussion).
By and big, dynamic microphones are extremely calm units as a result of the mix of transformer isolation and healthy, hanging sign lines all through, along with shielded, humbucking coils.
Therefore why not guitars? Instruments are once plagued by noise. Humbucking pickups are merely an incomplete (though important!) solution. The obvious alternative is always to move practicing the guitar collection to a healthy result, as being a microphone. A similar thought was printed this 2001 patent application such as Fender Standard Stratocaster Used?
