Even when I started, I had a vague idea of what the EQ options did. Sometimes you just gotta sit down and play with things.
The Vypyr is by far the easiest to use multi FX unit I've ever had. I don't know why, but I knew exactly how to use everything almost instantly. Usually there is a period of serious confusion where I turn to the manual to figure out what to do, but that didn't exist with the Vypyr. I eventually did turn to the manual to figure out exactly what a few of the amp sims and effects were, but I really didn't need to in order to use every feature.
It just seems like everything Peavy did with the interface made perfect sense to me. It's crazy to think that some people can't figure it out.
