An EV-5 worked the first time I stuck it into the PEDAL input.
The first footswitch I ever used worked as bypass, it is a session 10.
I hope that helped.
Oh also an FCB 1010 unit..(Berringer) I just sold one and it has 2 pedals on it stock standard…. I had an extra EV-5 working with them to modulate as many things as I could haha
