Seafoam Green Telecaster A guitar pickup is basically just like a vibrant microphone coil. For decades, active microphones have been sent with the voice coil mounted on the primary of the microphone's transformer, and not recommended to floor (‘floating'). The microphone's event is typically linked to the wire shield, which is attached to the mike amplifier's soil (see Rane's site for more discussion).
By and big, active microphones are very quiet units consequently of the mixture of transformer isolation and balanced, flying transmission lines for the duration of, along with shielded, humbucking coils.
So why don't you guitars? Guitars are notoriously overwhelmed by noise. Humbucking pickups are merely a partial (though important!) solution. Well-known answer is to float practicing the guitar pickup to a balanced production, as being a microphone. The same strategy was published that 2001 patent program like this Seafoam Green Telecaster?
