Bass For Beginners A guitar pickup is essentially much like a powerful mike coil. For decades, active microphones have now been wired with the style coil mounted on the principal of the microphone's transformer, and perhaps not called to floor (‘floating'). The microphone's case is typically attached to the wire guard, which is linked to the mike amplifier's ground (see Rane's site for more discussion).
By and big, active microphones are extremely calm devices consequently of the mixture of transformer isolation and balanced, hanging indication lines all through, in addition to protected, humbucking coils.
Therefore why don't you guitars? Instruments are notoriously overwhelmed by noise. Humbucking pickups are merely a partial (though essential!) solution. The obvious alternative would be to float the guitar collection to a balanced result, as being a microphone. An identical idea was printed this 2001 patent request such as Bass For Beginners?
