I'm using a Dunlop DVP4 pedal as an expression pedal with my Stomp and am having a problem with the sweep of the pedal. I'm sure it's a setting in there, but I can't seem to figure it out. If I start at the heel, the parameter I'm controlling changes until I get to the middle of the sweep and then the parameter goes the opposite way until I reach the toe. Here's an example:
I'm using the control as a volume pedal. At the heel, there is silence. As I move toward the toe, the volume increases until I get to the middle of the sweep of the pedal. The volume is now at 100%. As I continue toward the toe, the volume decreases. When it reaches the toe, the volume is again at 0.
This same phenomenon occurs with every effect - wah, whammy, etc. I can't figure out what I need to make the change. Any help is greatly appreciated.
Thanks.
