Peavey Special 212 A electric guitar pickup is basically similar to a dynamic microphone coil. For many years, energetic microphones have already been sent with the voice coil mounted on the principal of the microphone's transformer, and maybe not introduced to floor (‘floating'). The microphone's event is normally attached to the wire shield, which is linked to the microphone amplifier's soil (see Rane's site for more discussion).
By and large, energetic microphones are extremely calm devices as a result of the combination of transformer solitude and balanced, hanging indication lines throughout, in addition to shielded, humbucking coils.
Therefore why don't you instruments? Guitars are notoriously affected by noise. Humbucking pickups are just an incomplete (though important!) solution. The most obvious solution would be to float the guitar pickup to a healthy result, being a microphone. An identical idea was published this 2001 patent software such as Peavey Special 212?
