I recently purchased a Dunlop Crybaby Wah pedal from Guitar Center. When I got home, I set it up with my amp and guitar as the booklet said, with one cable going in the guitar from the pedal, and another from the pedal to the amp. I turned on my amp to start playing, and I activated the wah...and no wah effect. I don't have a power source for it because I didn't have enough money to buy one. The battery I put in it had been used before, but I think it should have worked a little bit. Does anyone have an idea as to why this happened?
Try using a new battery, and check that you put the cable in the right place
Okay. I've got a cable plugged into my amp input, the other end of which is going to the wah. I've got another cable going to the guitar from the other wah jack. I'm thinking it might be a battery problem though.
