I just bought my first Manji and found that the one hole is slightly more narrow than all the other holes by about the width of a couple playing cards. I’m a new player, so I don’t know if this is common or not, or if it will effect anything. The harp seems to blow and draw fine through the 1 hole. Any thoughts?
I just bought the same harmonica and it is just like you described. I guess that is the way they are made.
