8 Channel Usb Audio Interface A guitar pickup is actually much like a vibrant microphone coil. For decades, powerful microphones have been sent with the voice coil attached to the primary of the microphone's transformer, and not introduced to floor (‘floating'). The microphone's event is normally attached to the wire guard, which can be attached to the mike amplifier's surface (see Rane's site for more discussion).
By and big, powerful microphones are extremely quiet units consequently of the combination of transformer solitude and balanced, suspended transmission lines during, in addition to guarded, humbucking coils.
Therefore why don't you guitars? Instruments are notoriously affected by noise. Humbucking pickups are merely an incomplete (though crucial!) solution. The most obvious answer would be to float your guitar collection to a healthy productivity, just like a microphone.
