so you want a mode 1 controller, like a european style?

as far as I know you can do it, you would either have to switch the wires on the pots from one side to the other (the pot that sits cross ways, not the one that sits up and down), or switch the pots from one side to the other (I would check to see that they have about the same resistance before doing that), so it would be a pretty envolved mod. Chances are if you are careful with it, even if it doesn't work you can change it back. Also for about 50 bucks you could just get another controller that is a mode 1 controller =)
