Hi everyone, In late January I purchased a GK MB112 II online from the Guitar Center used gear page. I've been going direct for all my gigs recently so I didn't try it out until today. The amp turns on and the light goes from red to blue. When I try to play through it, nothing comes out. After about five minutes of messing with the settings, some super distorted notes suddenly came through. I turned it off and plugged it in to another outlet and couldn't get any sound to come out again. Any suggestions for what I might be able to do? I'm thinking that I won't be able to get any help from Guitar Center because because it's been about 80 days since I ordered it. I wish I had tested it out earlier though, because it seems that it must've came to me broken.
