I have a Monday gig in a house band. It's open mic and they usually have a weekly feature act, at which point the house band takes a break. We've already made it abundantly clear that we aren't providing our own personal gear as backline for ANYONE without the individual's permission. I turned my amp and tuner off. I'm running a ThunderFunk head and some custom Nahas cabs. Last night the feature was a collection of percussionists, along with a couple of guitar players and a vocalist. I saw one of the gp's roll in an amp before we left for break. When we returned to the back door,we were greeted with a wall of noise that was enough to keep us outside until called back in. Imagine my surprise when I plug in my bass and am immediately hit with a high pitched squeal. I look at my amp and see that both gains are maxed, every knob has been turned and the rig sounds like crap. I immediately confronted the guy who runs this show and he said no, no one used your amp, no, wait... maybe someone did. Why, is something wrong? I hit the ceiling. "*** do I have to do to get it through these stupid __'s heads not to touch my ____???" I was beyond pissed off that some clown decided while I was away that he would abuse my equipment. Plus going through the pocket in my rackbag where I keep my phone and other stuff. Fortunately I hadn't gone back in while he was playing it. *** is wrong with people? The amp and cabs seem okay. The guy in charge was very apologetic, even though he met my question "When one of these idiots breaks my gear, who is responsible for it?" with a blank look. The same thing had happened two weeks earlier when some guy decided to play my small rig like it was a Marshall stack, cranked farther than I ever would, while I was gone. Apparently they really didn't understand how I strongly felt about that not happening again. Last night I told the guy in charge "Let me make this simple. If someone, anyone else, touches my gear without my permission, I will ___ them up. Are we clear?" Took me about an hour to wind down. I make money with my gear and some jackass abusing it pissed me off to no end. It's disrespectful and you can bet that if he broke something it would be "My bad" followed by a dumbass look.
