Guitar String Manufacturers Usa A electric guitar pickup is basically just like a vibrant mike coil. For decades, active microphones have now been wired with the voice coil attached to the primary of the microphone's transformer, and perhaps not referenced to floor (‘floating'). The microphone's event is typically attached to the cable guard, which will be attached to the mike amplifier's ground (see Rane's web site for more discussion).
