Well, I disassembled it today and found the cause of our problem. Under abcd switches there is a "plank": long chip with buttons. And these buttons... Well, I don't know who decided it would be a good idea to use them in a device that would be smacked with legs. So there are these microbuttons like ppl who love to mess around with arduino use. You can find an image by googling "arduino button" tutorial. And these buttons (exactly under FS that are not clicking when pressed) are just not working properly anymore. Healthy button jumps back when you release it, while broken are just stuck. I don't get it how they still work at all. I don't know if there is a Line6 repair center here in my city and trying to get repair from shop might be as easy as buying a new one. Oh, and I have a gig tommorow. I'm really upset.
