A while back I had a site bookmarked, but I can't seem to find it now. They sold plates that hung off the side of Pedaltrain boards that provided a flat surface for mounting a wah or whammy or something of the sort. There was a single-width that would hold one wah and a double that would hold a whammy or 2 wahs. You could choose left-side or right-side for the side of the board you wanted it on. Anyone remember these or have a link at the ready?
