"This all-analog unit is a reproduction of the tone enhancing circuitry contained within the most widely used wireless system throughout the 1970's to mid 1980's, the Schaffer Vega Diversity System (SVDS). Emphatic users of the SVDS included Angus Young, David Gilmour, Eddie Van Halen, Carlos Santana, Peter Frampton, Peter Green, Joe Walsh, Don Felder, Elliot Randall, Jerry Garcia, Bob Weir... and an endless list of legends who are responsible for some of the best guitar parts ever recorded."
