I think that you are right about this, Ian. I am stubborn to a fault. People tell me many things, but I always want to find out for myself. In my searching for harmonica information I have encountered on two occasions someone claiming that when placed in a blind situation, even very good players frequently fail in identifying one type of harp from another. I don’t know if I believe that since neither claimant referenced the source for their suppositions.
I think I have reached a point where I can sit tight on purchasing any more harps and let time and practice tell what I really like.
