I started playing harmonica at 15 yrs old. I only just found out I can tune it, replace reeds , keep it going forever it, maintain it. The number of harmonicas I threw away and bought new ones which were very often, also out tune or not in concert pitch. Now I find out I completely wrong …all because of the INTERNET!
it’s a like miracle actually. I could rarely find a harmonica that would play in tune with the piano. Now I can actually tune them!
