DescriptionA Schaffer Vega Diversity System 63EX Wireless Receiver. The receiver is a rectangular box, with the front face containing adjustable knobs, inputs, and a small screen. Each side is black with a purple sticker. The back has several various inputs inset into metal.Inventor Ken Shaffer developed this wireless receiver with Vega Corporation to allow musicians more freedom while on stage. This was the first commercially successful wireless receiver – creating a seamless link between instruments and amplifiers. This SVDS 63EX model wireless receiver was used by David Gilmour during Pink Floyd’s heavily choreographed The Wall Tour in 1980. It was returned to Schaffer for re-tuning in early 1981.
Pink Floyd purchased five units and six spares (one "extra" hot-spare for David Gilmour) SVDS 63-EX guitar units directly from The Ken Schaffer Group, Inc., NY in 1979. The entire stage for The Wall tour was designed around (and dependent on) this wireless technology.
