Bass String Noise Frequency A best guitar pickup is basically similar to a vibrant microphone coil. For decades, powerful microphones have been wired with the voice coil attached to the primary of the microphone's transformer, and not introduced to surface (‘floating'). The microphone's case is usually connected to the wire guard, which can be attached to the mike amplifier's surface (see Rane's web site for more discussion).
By and large, dynamic microphones are extremely quiet units consequently of the combination of transformer solitude and balanced, hanging indication lines for the duration of, along with guarded, humbucking coils.
So why not guitars? Instruments are once plagued by noise. Humbucking pickups are only an incomplete (though important!) solution. The obvious solution would be to float the guitar pickup to a healthy result, just like a microphone. An identical strategy was published this 2001 patent software like this Bass String Noise Frequency?
