Springfield Guitar Center A electric guitar pickup is essentially similar to a dynamic microphone coil. For decades, dynamic microphones have been wired with the voice coil attached to the principal of the microphone's transformer, and not introduced to surface (‘floating'). The microphone's situation is typically linked to the cable guard, which can be connected to the mike amplifier's floor (see Rane's site for more discussion).
By and large, vibrant microphones are extremely calm devices as a result of the combination of transformer isolation and healthy, hanging transmission lines all through, along with guarded, humbucking coils.
Therefore why not guitars? Instruments are notoriously affected by noise. Humbucking pickups are just an incomplete (though essential!) solution. Well-known solution would be to float your guitar pickup to a healthy productivity, just like a microphone.
