Pearl Floor Tom A best guitar pickup is essentially much like an energetic mike coil. For many years, powerful microphones have now been wired with the voice coil attached with the primary of the microphone's transformer, and maybe not recommended to soil (‘floating'). The microphone's event is normally attached to the wire guard, which can be connected to the mike amplifier's floor (see Rane's website for more discussion).
By and big, powerful microphones are very quiet units as a result of the combination of transformer isolation and healthy, hanging sign lines for the duration of, in addition to shielded, humbucking coils.
So why not instruments? Guitars are once plagued by noise. Humbucking pickups are merely a partial (though essential!) solution. The most obvious answer is always to move practicing the guitar collection to a balanced production, just like a microphone. An identical idea was printed that 2001 patent application such as Pearl Floor Tom?
