Stevie Ray Vaughan Concert A electric guitar pickup is basically much like an energetic microphone coil. For decades, powerful microphones have now been wired with the voice coil mounted on the primary of the microphone's transformer, and perhaps not introduced to floor (‘floating'). The microphone's case is usually connected to the wire guard, that is connected to the microphone amplifier's ground (see Rane's website for more discussion).
