It is nice to own harmonicas in all the keys. Even though A, E and G have served me well in almost everything I have wanted to play. I bought this set a while ago and I´ve never been happy with it. Tone is very limited and muffled even, they are not bright, they don´t harmonize nicely. I have harmonicas from Bluesmaster, Jambone, Hohners-Marine Band - all are better than these. I have several Fender instruments and gear that I use and love. These are simply not good.
