http://www.sabrotone.com/wp-content/uploads/2012/12/SFT.gifI found this one awhile back when I was looking for this pedal. The layouts on this site are a lot clearer to read and seem more compact than the site I linked to, but maybe this will get you where you need to go. I'm looking at building this one for a friend soon myself. It says "verified" on it, but maybe one of the vero wizards could give it a once over and see if it looks legit.
