Snare Drum Grill A guitar pickup is basically just like a dynamic mike coil. For decades, powerful microphones have now been wired with the voice coil attached with the principal of the microphone's transformer, and maybe not referenced to ground (‘floating'). The microphone's event is normally attached to the cable shield, which can be connected to the mike amplifier's soil (see Rane's site for more discussion).
By and large, energetic microphones are very calm devices as a result of the mix of transformer isolation and healthy, hanging transmission lines for the duration of, as well as shielded, humbucking coils.
Therefore why not guitars? Guitars are once overwhelmed by noise. Humbucking pickups are just a partial (though important!) solution. Well-known answer is to float the guitar pickup to a healthy productivity, just like a microphone. An identical strategy was printed that 2001 patent software like this Snare Drum Grill?
