College educated....check Read manuals...check Watched YouTube...check Played with Editor...check Full understanding of how the footswitches work...NO! I have the HD500 in the mail, which is the first problem, but I'd like to "get" the system as best I can so I can move to instant tweaking. I don't think I get how the footswitches work. I thought it meant the top row would turn on/off the effects of current amp model and the bottom would bounce between amp models. Any help? What I'd like to do is have the bottom row - ABCD - control 4 different amp presets (with effects). The top row would control 4 effects for that preset. As I read up on it and use the editor, it looks like for any amp I can use 8 effects. That's fine, but how do I switch between ABCD then? I just can't rest not getting the big picture of things. Talk to me like I am two. Thanks!
