Les Paul 2017 A electric guitar pickup is basically similar to a dynamic microphone coil. For decades, powerful microphones have already been wired with the style coil mounted on the primary of the microphone's transformer, and maybe not introduced to floor (‘floating'). The microphone's case is typically attached to the wire shield, which will be linked to the microphone amplifier's surface (see Rane's website for more discussion).
By and big, vibrant microphones are very calm devices consequently of the mixture of transformer isolation and balanced, floating sign lines throughout, in addition to guarded, humbucking coils.
So why don't you instruments? Guitars are notoriously affected by noise. Humbucking pickups are merely a partial (though essential!) solution. The most obvious answer would be to move the guitar collection to a balanced production, being a microphone. A similar idea was published this 2001 patent program such as Les Paul 2017?
