Takamine Eg 463sc A guitar pickup is actually similar to a powerful microphone coil. For decades, dynamic microphones have now been wired with the style coil mounted on the primary of the microphone's transformer, and perhaps not recommended to surface (‘floating'). The microphone's situation is typically linked to the wire shield, that will be attached to the mike amplifier's surface (see Rane's internet site for more discussion).
By and large, vibrant microphones are very quiet products consequently of the mixture of transformer isolation and healthy, floating indication lines for the duration of, along with protected, humbucking coils.
So why not guitars? Instruments are notoriously affected by noise. Humbucking pickups are merely a partial (though important!) solution. Well-known answer is always to move the guitar pickup to a healthy result, as being a microphone. The same thought was printed that 2001 patent request like this Takamine Eg 463sc?
