Ozzy Osbourne Live A electric guitar pickup is actually just like a vibrant microphone coil. For decades, powerful microphones have now been sent with the voice coil mounted on the primary of the microphone's transformer, and maybe not referenced to surface (‘floating'). The microphone's situation is usually connected to the wire guard, that will be connected to the mike amplifier's floor (see Rane's site for more discussion).
By and big, dynamic microphones are extremely quiet devices consequently of the mix of transformer isolation and balanced, flying transmission lines throughout, as well as shielded, humbucking coils.
Therefore you will want to instruments? Guitars are notoriously overwhelmed by noise. Humbucking pickups are merely a partial (though essential!) solution. The obvious option is to float your guitar pickup to a balanced production, as being a microphone. The same thought was published this 2001 patent application like this Ozzy Osbourne Live?
