Voodoo Labs Ground Control A best guitar pickup is essentially just like a dynamic mike coil. For many years, powerful microphones have already been sent with the style coil attached with the primary of the microphone's transformer, and maybe not called to ground (‘floating'). The microphone's event is typically attached to the cable guard, which can be linked to the microphone amplifier's surface (see Rane's website for more discussion).
By and large, powerful microphones are very quiet products consequently of the mix of transformer isolation and healthy, hanging indication lines through the duration of, in addition to shielded, humbucking coils.
So why don't you guitars? Guitars are notoriously affected by noise. Humbucking pickups are just an incomplete (though essential!) solution. The most obvious solution would be to move your guitar pickup to a healthy production, just like a microphone. A similar thought was printed that 2001 patent software such as Voodoo Labs Ground Control?
