500 Series Compressor A guitar pickup is essentially similar to an energetic microphone coil. For decades, powerful microphones have already been sent with the voice coil mounted on the principal of the microphone's transformer, and not introduced to soil (‘floating'). The microphone's case is normally connected to the cable guard, that is linked to the mike amplifier's ground (see Rane's website for more discussion).
By and large, energetic microphones are very calm units as a result of the combination of transformer isolation and balanced, suspended sign lines during, as well as protected, humbucking coils.
So why don't you guitars? Guitars are once plagued by noise. Humbucking pickups are only a partial (though crucial!) solution. The most obvious answer would be to move the guitar collection to a healthy production, just like a microphone. A similar thought was published this 2001 patent request such as 500 Series Compressor?
