Did my second gig this weekend, went better than the first! We had our own sound System and our own sound guy so we actually had a balanced mix and no feedback. About 15 minutes before we started our rhythm guitar player couldnt get his amp to work and was starting to freak out! It was making no sound at all. We tried different cables and I tried my guitar and still nothing. I asked him if he had double checked all the settings and he said he had. He was getting ready to drive home and get his other amp when I started checking his settings and noticed he had his mute button engaged haha. That fixed it.
