Steve Vai For The Love Of God A guitar pickup is actually just like a powerful mike coil. For many years, dynamic microphones have now been sent with the style coil mounted on the primary of the microphone's transformer, and not called to floor (‘floating'). The microphone's case is typically linked to the wire guard, that will be attached to the microphone amplifier's floor (see Rane's website for more discussion).
By and big, active microphones are extremely calm units as a result of the mixture of transformer solitude and balanced, floating indication lines all through, along with protected, humbucking coils.
So why not guitars? Guitars are once plagued by noise. Humbucking pickups are only a partial (though crucial!) solution. The most obvious solution is to float the guitar collection to a healthy productivity, being a microphone. A similar idea was printed this 2001 patent application like this Steve Vai For The Love Of God?
