It seems like everytime I play a show I have some stupid mistake. Our first show my band played, I forgot to tune back up from D, and I did it mid song (Big mistake). It didn't sound pretty. This show last night, my guitarist and I were messing around with a solo at low volume before the show at practice, so we had our guitars turned down low. When I got to the show, I forgot I had it set that way. I keep thinking "Wow, my amp sounds really quiet tonight, whats up", then I turn the volume knob on my bass and BOOM! I had been conpensating for the low volume by turning my amp up, so when I turned the bass volume up, it was loud. I turned it down a bit and finished the set in bassy glory. All these are just dumb mistakes though. I'm going to make up a saftely list to go through before every set now. Anybody esle made some stupid mistakes?
