Nah, the WoS was long before my time with them, that was not a real touring system (as they soon found out) but more of an experiment. With the development of monitor systems (WoS was sans-monitors so they could get real time sound - p.s. they didn't, that slew rate problem, Ohm could have told them, but hey, they don't listen) but it was a Big Bear Experiment, which like a lot of BBEs, was half awesome, have disaster. But it gave them (and others) the need to develop real systems, so from there came UltraSound, and from there the people at Meyers, who make the boxes that they use now. Which, BTW, are awesome.
