I need some help, I just bought a new Epic (used) through guitar center, and a couple of things are irking me and I'm not positively sure of the control layout, I think something may be broken. Here's a pic
4 most obviously seems to be volume, 2 seems to be a tone, 3 doesn't seem to do anything at all. 1 is weird, in that when it is turned up it is nice and loud and sounds great, but when I turn it down the sound goes away, leading me to believe that this may be the pan and that a pickup is out or something. Any help would be much appreciated; I want to fix the problem if possible, if not then I'd really like to send it back! which would suck. Please help
