Marroon 5 Tour A best guitar pickup is essentially similar to a dynamic microphone coil. For many years, powerful microphones have already been sent with the style coil attached to the primary of the microphone's transformer, and not called to surface (‘floating'). The microphone's case is normally connected to the wire guard, that is attached to the mike amplifier's surface (see Rane's internet site for more discussion).
By and big, active microphones are extremely quiet products as a result of the mix of transformer isolation and balanced, flying transmission lines for the duration of, along with guarded, humbucking coils.
So why don't you guitars? Instruments are once affected by noise. Humbucking pickups are merely a partial (though crucial!) solution. The most obvious alternative is to move the guitar collection to a healthy result, being a microphone. A similar thought was published this 2001 patent software such as Marroon 5 Tour?
