I had a similar problem on a little marshall tube amp a few years ago. I think the problem turned out to be a failing tube socket. I assume the Spider Valve is tube driven? The first thing I would check would be the tubes themselves. And, of course, don't forget to bias the new tubes...

You would have much more luck finding the info you need on the line6 forums. That amp is 100% line6.
