I’m a beginner hoping for a little advice. I just got a new Hohner MB Crossover (G) and found a strange sound on the 2-hole draw. I can play the note, but it’s intermitently accompanied by a fluttering, flappy, chirpy sound. I don’t know if it’s me, or the harp. I made a small recording here. I intentionally tried to get the odd sound, not for the note to sound good 😉 Anyone know what that is? Any advice is appreciated. Thanks
