Marty Friedman Jackson A guitar pickup is essentially much like a powerful microphone coil. For decades, active microphones have already been sent with the voice coil mounted on the principal of the microphone's transformer, and not introduced to surface (‘floating'). The microphone's event is typically attached to the cable guard, which can be connected to the mike amplifier's ground (see Rane's web site for more discussion).
By and large, dynamic microphones are very calm products as a result of the mix of transformer isolation and balanced, suspended transmission lines all through, along with protected, humbucking coils.
So you will want to guitars? Instruments are notoriously affected by noise. Humbucking pickups are merely an incomplete (though essential!) solution. The obvious alternative is to move your guitar pickup to a healthy production, just like a microphone. The same strategy was printed this 2001 patent application such as Marty Friedman Jackson?
