Shure M44 7 Needle A best guitar collection is actually similar to a dynamic mike coil. For decades, vibrant microphones have been sent with the voice coil mounted on the principal of the microphone's transformer, and maybe not recommended to surface (‘floating'). The microphone's event is typically attached to the cable shield, which is connected to the microphone amplifier's surface (see Rane's internet site for more discussion).
