Tony, I have two single footswitches and one technics switch that has four switches on one board. Both work great. Also I have one old big heavy switch made by Yamaha that works good also. The KN's are made to take up to six switches at one time. The only thing that they wont do is turn Ruthie on or off. At least when I look at the window that asigns the functions to each one there is none that says Ruthie.
