Holy Grail Neo A guitar pickup is basically similar to an energetic microphone coil. For many years, energetic microphones have already been sent with the voice coil attached to the principal of the microphone's transformer, and perhaps not referenced to soil (‘floating'). The microphone's situation is typically connected to the wire guard, which can be linked to the mike amplifier's soil (see Rane's website for more discussion).
By and large, energetic microphones are extremely quiet units consequently of the mixture of transformer isolation and balanced, flying sign lines throughout, as well as shielded, humbucking coils.
So you will want to instruments? Instruments are notoriously overwhelmed by noise. Humbucking pickups are only a partial (though important!) solution. The obvious option would be to float practicing the guitar collection to a balanced production, as being a microphone. An identical thought was published this 2001 patent request such as Holy Grail Neo?
