Ibanez Rg 7 String A electric guitar collection is actually much like a dynamic mike coil. For decades, active microphones have already been sent with the style coil mounted on the primary of the microphone's transformer, and perhaps not called to floor (‘floating'). The microphone's event is typically attached to the wire guard, that will be attached to the mike amplifier's surface (see Rane's website for more discussion).
By and big, dynamic microphones are extremely calm devices consequently of the mixture of transformer isolation and healthy, flying transmission lines for the duration of, as well as shielded, humbucking coils.
Therefore why don't you guitars? Instruments are once overwhelmed by noise. Humbucking pickups are just an incomplete (though crucial!) solution. The most obvious option would be to float the guitar pickup to a healthy result, being a microphone. A similar idea was published this 2001 patent request such as Ibanez Rg 7 String?
