Yes, the whole pedal is turnable, over about a 70 degree range, on a 
circular base. The center of the twisting motion is aligned with the 
leg bone, more or less, so it is possible to adjust the up-down 
position and left-right position independently, with practice. I play 
standing up and I've put a lot of weight on it. I am not sure how 
easy it would be to use with a guitar on your knee!

There is a potentiometer in it, in addition to the potentiometer that 
was already in the pedal for the normal up-down axis. Two TRS jacks, 
I plug into an old Yamaha MCS2 MIDI fader box. Does the EDP use 
potentiometer pedals?

Yes, maybe a pressure sensor on the ball of the foot. Or five little 
tiny toe-pedals... I remember ads for a wah-wah pedal that didn't 
move, it was a little blob, you stood on it and shifted your weight 
around. Anyone ever try one of those?
