Hey people, first of all, sorry for my english, i'm from Brazil.

So, i bought this pedal about 2 years ago from ebay, and since i got it, i couldn't take a nice sound from it, it seems more like a volume pedal than a wah pedal. When my heel is down, the volume gets way lower, and if a change the right knob position till this problem is resolved, the wah range turns into s**t. I don't know what's happening, i read reviews over the internet and everyone seems to like this pedal, but some people complain about the same problem i have. So, can you guys help me or should i buy a new pedal? =(
