Snare Drum Damper A guitar pickup is actually just like a vibrant microphone coil. For decades, vibrant microphones have already been sent with the style coil attached with the primary of the microphone's transformer, and not called to ground (‘floating'). The microphone's event is usually connected to the cable guard, which is attached to the microphone amplifier's ground (see Rane's website for more discussion).
By and big, dynamic microphones are very calm products consequently of the mix of transformer isolation and balanced, suspended transmission lines during, as well as shielded, humbucking coils.
Therefore why don't you guitars? Guitars are once affected by noise. Humbucking pickups are just an incomplete (though important!) solution. The obvious solution is to move the guitar collection to a balanced productivity, as being a microphone. The same idea was published this 2001 patent program such as Snare Drum Damper?
