Left Handed Semi Hollow Guitar A guitar pickup is basically just like a powerful mike coil. For many years, powerful microphones have already been wired with the style coil attached to the principal of the microphone's transformer, and not recommended to soil (‘floating'). The microphone's case is usually connected to the wire guard, which will be attached to the mike amplifier's ground (see Rane's website for more discussion).
