Guitar Speaker Cabinet Paint A electric guitar pickup is actually much like an energetic mike coil. For decades, energetic microphones have already been wired with the voice coil mounted on the primary of the microphone's transformer, and not referenced to surface (‘floating'). The microphone's case is typically attached to the cable shield, that is linked to the microphone amplifier's surface (see Rane's web site for more discussion).
By and big, energetic microphones are very calm devices consequently of the combination of transformer solitude and healthy, flying transmission lines during, in addition to guarded, humbucking coils.
So why don't you instruments? Guitars are once overwhelmed by noise. Humbucking pickups are merely a partial (though essential!) solution. The obvious solution is always to float your guitar pickup to a healthy production, as being a microphone. The same strategy was printed this 2001 patent software such as Guitar Speaker Cabinet Paint?
