Acoustic Guitar Covers A best guitar pickup is actually just like a dynamic microphone coil. For decades, powerful microphones have now been sent with the style coil attached to the principal of the microphone's transformer, and not introduced to soil (‘floating'). The microphone's situation is typically connected to the cable shield, which can be linked to the mike amplifier's surface (see Rane's site for more discussion).
By and big, powerful microphones are extremely calm units consequently of the mix of transformer solitude and healthy, floating transmission lines throughout, along with shielded, humbucking coils.
So why not guitars? Guitars are notoriously overwhelmed by noise. Humbucking pickups are just a partial (though important!) solution. Well-known option would be to move your guitar pickup to a balanced output, as being a microphone. The same strategy was published this 2001 patent request such as Acoustic Guitar Covers?
