As the title says, at what point did you feel competent enough to join a band? I’ve been playing the guitar for almost 2 years now, and feel like I hit a bit of a plateau, and I’m thinking joining a band might help. At the same time, I don’t really feel like I am good enough to play with others.
Unless you’re trying to get into some kind of crazy prog/jazz band, ability is less important than attitude. If you put in effort, listen to feedback, and wrangle your ego a little you’ll do fine. And if everyone’s a jerk, that’s not the band for you.
edit: also, set up fast and help the drummer haul their shit in
