I think having some practice runs would be helpful. If you just recorded your own stereo, use the settings, use the menus, get familiar with what you can do when recording and what you can’t do while recording. I would just try to learn the gear that you’re using. I haven’t been taping too long, but doing it is really the only way to get more familiar with it. Being at shows and not knowing how to work out an issue is very stressful, but it’s also how I learn how to not do things as well. Have fun, and welcome to the rabbit hole!
