Guitar Center Westheimer A guitar collection is actually similar to an energetic mike coil. For decades, dynamic microphones have now been sent with the voice coil attached to the primary of the microphone's transformer, and maybe not called to floor (‘floating'). The microphone's event is usually attached to the wire guard, that will be connected to the microphone amplifier's floor (see Rane's web site for more discussion).
By and big, energetic microphones are very calm devices as a result of the mixture of transformer isolation and healthy, suspended indication lines during, along with guarded, humbucking coils.
So why don't you guitars? Instruments are notoriously affected by noise. Humbucking pickups are merely an incomplete (though important!) solution. The most obvious option is always to float your guitar collection to a balanced output, being a microphone. A similar strategy was published that 2001 patent request such as Guitar Center Westheimer?
