Scott,
It's the Digitech FS300, which has a single, 1/4-inch, stereo connection on the back of the switch. I checked the schematic diagram and you can pretty much use it for any function, and if you wish, put together a modified, three-line cable that can go to three different devices. The switch was about $39 at the local music store.
