Roland Vp 03 A electric guitar pickup is actually similar to a dynamic microphone coil. For many years, vibrant microphones have been wired with the voice coil attached to the primary of the microphone's transformer, and perhaps not referenced to floor (‘floating'). The microphone's case is typically linked to the cable guard, that is connected to the microphone amplifier's soil (see Rane's internet site for more discussion).
By and big, dynamic microphones are very quiet devices as a result of the mixture of transformer isolation and balanced, hanging indication lines for the duration of, along with guarded, humbucking coils.
So you will want to instruments? Guitars are notoriously overwhelmed by noise. Humbucking pickups are just a partial (though crucial!) solution. The obvious answer is always to move your guitar pickup to a balanced production, as being a microphone. An identical idea was printed this 2001 patent request such as Roland Vp 03?
