I'd like to see some pedals override the volume/wah feature on this pedal... I've been using the Digitech Whammy pedal clone on here, but I can't get the tones I want because there's no way to use it as an expression pedal on the fly? Is this a possible integration for the future, or is there another way to assign pitch shift to the expression pedal on it? I'd also like a tremelo on this pedal, with it speeding up as the expression pedal moves down. Many thanks, Kai.
