Wichita Music Store A electric guitar collection is actually similar to an energetic microphone coil. For decades, vibrant microphones have now been wired with the voice coil attached with the primary of the microphone's transformer, and maybe not referenced to floor (‘floating'). The microphone's event is normally linked to the wire guard, that will be connected to the microphone amplifier's ground (see Rane's website for more discussion).
By and big, active microphones are very quiet devices as a result of the mixture of transformer solitude and healthy, flying sign lines throughout, in addition to guarded, humbucking coils.
So why don't you guitars? Instruments are once plagued by noise. Humbucking pickups are only an incomplete (though essential!) solution. The most obvious answer would be to float your guitar collection to a balanced output, as being a microphone. A similar idea was printed that 2001 patent software like this Wichita Music Store?
