Hey I'm Alec. I have never used a forum before, so I hope I'm doing everything right. I am a complete beginner and I was wondering if someone can help me out please: I just bought a new concertina and it makes this strange vibrating noise when transitioning from pulling out to pushing in (or vise versa) while holding the same button. It is really only noticeable on the lowest notes. Is this normal? This is the first concertina that I have ever played.
I attached a sound recording.
