Red Hott Chat A guitar collection is essentially much like an energetic microphone coil. For many years, dynamic microphones have been wired with the style coil attached with the principal of the microphone's transformer, and not introduced to surface (‘floating'). The microphone's event is typically connected to the wire guard, that is attached to the mike amplifier's surface (see Rane's internet site for more discussion).
By and big, vibrant microphones are very quiet products consequently of the combination of transformer isolation and healthy, hanging sign lines all through, as well as protected, humbucking coils.
Therefore why not guitars? Instruments are notoriously plagued by noise. Humbucking pickups are only an incomplete (though crucial!) solution. The obvious option is to float the guitar pickup to a balanced production, being a microphone. A similar thought was published this 2001 patent application such as Red Hott Chat?
