Mine is an expression pedal- I use it for wah, delay mix & feedback, and looper volume. It was modded by ThruTone for the right pot and taper. The small 'kick switch' on the upper left of the pedal will allow it to control a whole other set of things.I see both of you have the EB VOL. After being a Morley guy for decades, I decided to give the EB a try, and so far I love it. The action is great, and the taper on the pedal is much better. The downside is they are huge.
