I've been a gigging bass player for almost 20 years. Before yesterday, I'd never had a piece of gear fail on me at a show. Never even broken a string, honestly. I typically only bring one bass with me, and trust that things will work as they should. Never again! My bass started crackling at my gig yesterday, then completely stopped working. Fortunately, it was at the end of the set, and there was a piano at the venue so we finished up with some songs I play keys on. Still, it was very embarrassing and I will be bringing a backup bass to every gig I do from now on! Also a bag with extra cables, strings, and my DI/preamp in case something unexpected happens. You gotta be prepared for anything, as I learned the hard way yesterday!
