Recently I bought Jim Dunlop custom shop rack wah module with foot controller and I have some "things" with it:
It's strange way turns on and off + wah doesn't react (or react incorrectly?) controllers pedal movement..

It is difficult for me to explane.

Please, help me how to fix this problems?

And sorry for my English.
