Martin M 36 A electric guitar collection is actually just like a dynamic mike coil. For decades, dynamic microphones have already been wired with the voice coil attached to the principal of the microphone's transformer, and not introduced to surface (‘floating'). The microphone's event is typically linked to the wire guard, which can be linked to the microphone amplifier's soil (see Rane's site for more discussion).
By and big, vibrant microphones are very quiet devices as a result of the mix of transformer isolation and balanced, suspended sign lines through the duration of, as well as protected, humbucking coils.
So you will want to guitars? Guitars are notoriously affected by noise. Humbucking pickups are only a partial (though crucial!) solution. The most obvious solution is to move your guitar pickup to a balanced output, being a microphone. A similar idea was published this 2001 patent program such as Martin M 36?
