Drum Head Fish A electric guitar pickup is basically similar to a powerful microphone coil. For decades, active microphones have been wired with the style coil attached with the principal of the microphone's transformer, and not referenced to ground (‘floating'). The microphone's event is normally attached to the cable guard, which can be linked to the microphone amplifier's ground (see Rane's web site for more discussion).
By and large, vibrant microphones are very calm devices consequently of the mix of transformer isolation and healthy, hanging sign lines all through, along with protected, humbucking coils.
Therefore why not guitars? Guitars are once plagued by noise. Humbucking pickups are merely an incomplete (though important!) solution. Well-known alternative is always to float the guitar pickup to a healthy production, just like a microphone. The same thought was printed that 2001 patent application like this Drum Head Fish?
