Joeco Black Box A electric guitar pickup is basically just like an energetic microphone coil. For many years, active microphones have already been sent with the voice coil attached to the principal of the microphone's transformer, and perhaps not called to soil (‘floating'). The microphone's situation is typically linked to the wire shield, that will be connected to the mike amplifier's surface (see Rane's site for more discussion).
By and big, active microphones are very quiet products as a result of the combination of transformer solitude and balanced, suspended transmission lines all through, as well as shielded, humbucking coils.
So why not instruments? Instruments are once overwhelmed by noise. Humbucking pickups are only a partial (though important!) solution. The most obvious option would be to move practicing the guitar pickup to a healthy result, being a microphone. An identical thought was printed that 2001 patent program like this Joeco Black Box?
