Aturia Analog Factory A electric guitar pickup is actually much like an energetic mike coil. For decades, vibrant microphones have been wired with the style coil attached with the primary of the microphone's transformer, and not introduced to surface (‘floating'). The microphone's event is typically attached to the wire shield, that will be connected to the microphone amplifier's soil (see Rane's website for more discussion).
By and big, dynamic microphones are very calm products as a result of the mix of transformer isolation and balanced, hanging sign lines throughout, as well as shielded, humbucking coils.
Therefore why not guitars? Instruments are notoriously plagued by noise. Humbucking pickups are merely a partial (though important!) solution. Well-known option is always to move your guitar pickup to a balanced production, as being a microphone. An identical idea was published that 2001 patent software like this Aturia Analog Factory?
