Komplete Kontrol 49 A guitar pickup is actually just like a vibrant mike coil. For many years, powerful microphones have now been wired with the voice coil mounted on the primary of the microphone's transformer, and maybe not referenced to floor (‘floating'). The microphone's case is typically connected to the wire shield, that is linked to the mike amplifier's soil (see Rane's website for more discussion).
By and big, active microphones are very quiet units as a result of the mix of transformer solitude and healthy, flying transmission lines for the duration of, as well as shielded, humbucking coils.
Therefore why not guitars? Guitars are notoriously plagued by noise. Humbucking pickups are just an incomplete (though important!) solution. The most obvious solution is always to float your guitar pickup to a healthy production, just like a microphone. A similar thought was printed that 2001 patent request like this Komplete Kontrol 49?
