@Cadgirl & @N-lightMike that makes 3 of us with hearing aids, but I go days without wearing them, because it’s just me and the dog typically. But, I don’t play or sing loudly usually, but I’ve heard many with hearing difficulties do that. That might be part of my problem hearing pitch. Mike, what are you referring to when you say you use the guitar as a tuning fork?
