Well, you see, I've had a crappy Lyon wah pedal sitting around my house for the past 3 years, and I wanna put it to some use. And I really want a volume pedal, so well...I thought I'd try and build one. I mainly only plan on using the frame of it. It doesnt seem that hard to me, but I'm probably just being naive. Any ideas or diagrams i could go off of?

any information or ideas would be helpful, I just dont feel like blowing 80 bucks on that ernie ball one.
