Yeah, I gotta tell you guys, I am extremely interested in this stuff. I HAVE to know how stuff works, it's a bit of a compulsion. The best way to figure out How It Works, is to make it yourself. Then you try to figure out how it can be done better! Seriously that BYC site has a Rat clone, I miss my Rat...stolen. I could very easily go get another, but now that I know these guys are out there, I think I will build it myself, besides they include in their kit the most popular mods that are usually done to the Rat pedal, so it is like spending money to save money, if you know what I mean!
