Korean Handwriting Keyboard A electric guitar collection is essentially similar to a dynamic mike coil. For decades, dynamic microphones have now been wired with the voice coil attached with the primary of the microphone's transformer, and perhaps not introduced to floor (‘floating'). The microphone's case is usually attached to the cable shield, which is attached to the mike amplifier's ground (see Rane's site for more discussion).
By and large, vibrant microphones are very calm units as a result of the mixture of transformer solitude and balanced, suspended transmission lines for the duration of, in addition to shielded, humbucking coils.
Therefore why not guitars? Guitars are notoriously plagued by noise. Humbucking pickups are merely a partial (though essential!) solution. The obvious solution would be to float your guitar pickup to a healthy production, being a microphone. The same thought was printed that 2001 patent application like this Korean Handwriting Keyboard?
