I bought a Hohner Marine band crossover. Great sound and very easy to bend. But there’s one big problem. Sometimes it’s impossible to get a sound out of the one hole blow and the one hole draw is also very difficult and the tone is weak and “creaky”. (not as bad as one hole blow though.) I don’t know, it’s as if the reed is stuck or something. And it sort of comes and goes. All the other holes are just fine.
I don’t have any experience how to fix harmonicas whatsoever. Should I open it up? What shall look for? Any help is highly appreciated.
