Moog Theremin Kit A electric guitar pickup is actually similar to a powerful microphone coil. For many years, vibrant microphones have been wired with the voice coil mounted on the primary of the microphone's transformer, and maybe not introduced to floor (‘floating'). The microphone's situation is usually linked to the cable guard, that is attached to the microphone amplifier's soil (see Rane's web site for more discussion).
By and big, dynamic microphones are extremely calm products consequently of the mixture of transformer solitude and healthy, suspended transmission lines throughout, along with shielded, humbucking coils.
So why don't you guitars? Guitars are notoriously overwhelmed by noise. Humbucking pickups are just a partial (though crucial!) solution. The obvious alternative is to float the guitar pickup to a balanced output, as being a microphone. An identical thought was printed that 2001 patent application such as Moog Theremin Kit?
