I picked this up from a kid on Craigslist yesterday. He used it with a guitar through a 10A Crate combo and couldn't figure out why it sounded so bad. All I had to do was take it apart and clean the pots and she works perfectly. Oh Yeah, I only paid $25 for it.

I would have just given it to my friend. I'm kinda glad I never tried to fool around with it when I had it for the sake of my speakers!
