I worry about the same thing, over tuning. I down loaded a tuner that I use on my IPhone. It gives me a full range of tones. Try it out and see if you like it. https://apps.apple.com/us/app/instuner-free-chromatic-tuner/id603425027?platform=iphone It’s free and I use it with the tuner that I have clipped on my guitar. Just a little safety net. Glad to hear you didn’t put your eye out when that string broke and don’t worry about the neck. I’m sure no harm was done.
