that's also one of my problems, I got the sp1-r with toes switch but I bought it off EBay thought it would work with the helix rack. this one's got a polarity switch.

thanks everyone for the reply. I also forgot to add, I pulled the trigger to soon and I got me the sp1-r which I guess is for axefx2. Doesn't work with the helix rack. any way can I rewire this instead? thanks once again for the help.

just got the helix rack, how do i setup expression pedal to control wah and other effects? is it supposed to be plug and play? thanks in advAnced
