Mark IIIs use two separate footswitches. The one that plugs into the jack on the front panel switches between Lead and either R1 or R2 (depending on whether the Middle knob is pulled or not). There is a second footswitch jack on the underside of the chassis on the back near the power tubes; a switch plugged into this jack will control switching between R1 and R2. I just use two separate footswitches with my Mark III. Some people use homebrew switches that are basically two separate footswitches in one box.
