Tech 21 Se Case A best guitar pickup is basically much like a dynamic microphone coil. For decades, powerful microphones have been sent with the style coil attached with the principal of the microphone's transformer, and maybe not recommended to floor (‘floating'). The microphone's event is usually connected to the cable guard, that will be linked to the mike amplifier's surface (see Rane's site for more discussion).
By and big, powerful microphones are very quiet products as a result of the combination of transformer solitude and healthy, suspended sign lines during, in addition to shielded, humbucking coils.
So why don't you guitars? Guitars are notoriously affected by noise. Humbucking pickups are only an incomplete (though important!) solution. Well-known option would be to move your guitar pickup to a balanced productivity, being a microphone. A similar strategy was published this 2001 patent request such as Tech 21 Se Case?
