I have the sanpera 2, and my Wah pedal on it does not work. Is there a certain way to activate it or is my pedal defective?
not saying your stupid but have you tried pressing down the pedal really hard onto the switch? The sanperas are hard to activate and theres acctaully a mod you can do to make it easier. If its not that then it could be a bad solder joint or defective.
yeh my line 6 FBV express pedal was like that. i was sitting down and putting all my weight on it and it wouldn't activate.. i stood up and put more pressure on it and it worked.

EDIT: You gotta push hard on the toe standing up
