Did a quick search and nothing turned up... May just be the search tools. But anyway, I've been hearing good things about the Dunlop Volume X pedal. I like its size, build, and capability to be an expression pedal. My question is if it can switch between both capabilities on the fly. Like for one song, be using it as a volume for swells, and another to be using it as an expression pedal for another sound. I don't know if this is possible. Anyone have experience with this pedal?
