Walrus Audio Voyager A guitar collection is actually similar to an energetic microphone coil. For decades, vibrant microphones have been wired with the style coil mounted on the principal of the microphone's transformer, and perhaps not called to surface (‘floating'). The microphone's case is typically attached to the cable shield, which can be connected to the microphone amplifier's floor (see Rane's site for more discussion).
By and large, powerful microphones are extremely quiet devices as a result of the combination of transformer solitude and healthy, floating transmission lines throughout, in addition to protected, humbucking coils.
So why don't you guitars? Guitars are once plagued by noise. Humbucking pickups are merely an incomplete (though important!) solution. The most obvious option would be to move your guitar collection to a balanced output, just like a microphone. The same thought was published this 2001 patent request like this Walrus Audio Voyager?
