It’s always impressive when you see someone on stage quickly retune their guitar between songs; whenever I see that, I always think, “there is an experienced musician.” It is especially impressive if you, like most people who are new to the guitar, have to perform several iterations of plucking and tuning before even getting one string in tune.
You can get by without this skill, since tuners are cheap and plentiful. But, besides the advantage of not always being dependent on a tuner and being able to quickly re-tune if you go out of tune while playing live, is not having to deal with the nagging feeling, in the back of your mind, that you can’t tune well. It’s just another thing to make you feel like a beginner and diminish your confidence. As guitarists, the fewer things we have eating away at our confidence the better.
