Hello,
I’m new to the forum. I own a Bastari 20 button concertina. I’ve had it for 30 years and only recently started to give it serious attention. One of the values leaks, so that when you push or pull on the bellow, it plays without depressing a button. The button is the A, right side, top row, 4th button in from the left. It sounds both the push and the pull notes. I’ve taken it apart three times and can’t see how the valves/reeds appear any different from the buttons that are working, and I’m stumped and frustrated. Can anyone offer any advice or point me to any information?
Much appreciated,
Thank you,
Jaime
