Ben Bruce Guitar A best guitar collection is actually similar to a dynamic mike coil. For many years, active microphones have now been sent with the style coil attached with the primary of the microphone's transformer, and perhaps not recommended to ground (‘floating'). The microphone's situation is normally connected to the cable shield, which can be attached to the mike amplifier's floor (see Rane's site for more discussion).
By and large, active microphones are very quiet units consequently of the combination of transformer isolation and balanced, suspended transmission lines throughout, along with shielded, humbucking coils.
So why don't you guitars? Instruments are once plagued by noise. Humbucking pickups are merely a partial (though crucial!) solution. The obvious answer is to float practicing the guitar collection to a balanced production, being a microphone. The same thought was printed that 2001 patent request like this Ben Bruce Guitar?
