Synyster Custom S A best guitar collection is essentially similar to a dynamic mike coil. For decades, active microphones have been sent with the voice coil mounted on the principal of the microphone's transformer, and maybe not introduced to soil (‘floating'). The microphone's situation is normally attached to the wire shield, which is attached to the microphone amplifier's ground (see Rane's internet site for more discussion).
By and big, active microphones are extremely quiet devices consequently of the combination of transformer isolation and balanced, flying transmission lines throughout, in addition to guarded, humbucking coils.
Therefore why not guitars? Guitars are notoriously overwhelmed by noise. Humbucking pickups are merely a partial (though crucial!) solution. The obvious answer is to float your guitar collection to a healthy output, as being a microphone. A similar idea was published this 2001 patent application such as Synyster Custom S?
