Whats wrong with my amp ?

Im no guitar expert but most cases could be a wire or a fuse. if it has fuses no point in going to hardware store for new one cause they build most music electronics to be no good after fuses blow. now if its a wire u may be able to cut and twist em back together. u gotta cross ur negatives wit ur negatives and ur positives wit ur positive and use black tape to hold it together. go to guitarcenter.com if u just wanna buy it new or used.
