Taylor 214e Deluxe A best guitar pickup is actually much like a powerful microphone coil. For decades, vibrant microphones have already been wired with the voice coil attached to the primary of the microphone's transformer, and perhaps not recommended to ground (‘floating'). The microphone's event is typically attached to the wire guard, which is attached to the microphone amplifier's ground (see Rane's site for more discussion).
By and large, dynamic microphones are extremely calm products as a result of the combination of transformer solitude and balanced, floating sign lines all through, as well as guarded, humbucking coils.
So why don't you guitars? Instruments are notoriously affected by noise. Humbucking pickups are only a partial (though crucial!) solution. The most obvious alternative is always to float the guitar pickup to a balanced result, as being a microphone. The same strategy was published this 2001 patent application such as Taylor 214e Deluxe?
