Focusrite Scarlett Solo Audio Interface A best guitar pickup is basically much like a powerful microphone coil. For decades, dynamic microphones have been wired with the style coil attached with the primary of the microphone's transformer, and not called to floor (‘floating'). The microphone's situation is typically connected to the wire shield, which can be linked to the mike amplifier's soil (see Rane's site for more discussion).
By and big, powerful microphones are extremely calm devices as a result of the mix of transformer solitude and healthy, floating sign lines during, as well as protected, humbucking coils.
Therefore why don't you instruments? Guitars are notoriously plagued by noise. Humbucking pickups are merely an incomplete (though essential!) solution. Well-known solution would be to move the guitar pickup to a balanced productivity, being a microphone. An identical idea was printed this 2001 patent software such as Focusrite Scarlett Solo Audio Interface?
