Install Surround Speakers In Ceiling A guitar pickup is basically similar to a vibrant mike coil. For decades, active microphones have been wired with the voice coil attached with the primary of the microphone's transformer, and perhaps not introduced to surface (‘floating'). The microphone's situation is normally linked to the cable guard, which is attached to the microphone amplifier's surface (see Rane's site for more discussion).
