Nylon Strings On Acoustic A electric guitar pickup is actually similar to a powerful mike coil. For decades, powerful microphones have already been sent with the voice coil attached to the primary of the microphone's transformer, and perhaps not recommended to soil (‘floating'). The microphone's event is typically connected to the wire shield, that is attached to the microphone amplifier's surface (see Rane's site for more discussion).
By and big, powerful microphones are very quiet units as a result of the mixture of transformer solitude and healthy, flying sign lines throughout, as well as shielded, humbucking coils.
So why not guitars? Guitars are notoriously plagued by noise. Humbucking pickups are only an incomplete (though important!) solution. Well-known option is to move practicing the guitar collection to a healthy productivity, just like a microphone. An identical idea was published this 2001 patent application like this Nylon Strings On Acoustic?
