Danelectro French Toast A electric guitar pickup is actually just like a vibrant mike coil. For decades, vibrant microphones have been sent with the voice coil attached with the primary of the microphone's transformer, and perhaps not recommended to soil (‘floating'). The microphone's situation is normally connected to the wire guard, which can be linked to the mike amplifier's surface (see Rane's website for more discussion).
By and large, dynamic microphones are very calm products consequently of the combination of transformer isolation and healthy, hanging sign lines throughout, in addition to protected, humbucking coils.
So why don't you guitars? Instruments are notoriously plagued by noise. Humbucking pickups are only an incomplete (though essential!) solution. Well-known answer is always to float practicing the guitar collection to a balanced output, being a microphone. A similar strategy was published this 2001 patent program like this Danelectro French Toast?
