Kings Of Chaos A guitar pickup is actually just like a powerful microphone coil. For decades, dynamic microphones have now been wired with the voice coil mounted on the primary of the microphone's transformer, and maybe not recommended to floor (‘floating'). The microphone's event is usually linked to the cable guard, which will be connected to the microphone amplifier's surface (see Rane's website for more discussion).
By and big, dynamic microphones are very calm products as a result of the mixture of transformer isolation and balanced, suspended sign lines throughout, in addition to protected, humbucking coils.
So why not instruments? Guitars are once plagued by noise. Humbucking pickups are just a partial (though important!) solution. Well-known alternative would be to float practicing the guitar collection to a healthy production, as being a microphone. An identical idea was printed this 2001 patent request like this Kings Of Chaos?
