This is a multi-part message in MIME format. Hi folks,=20 I'm thinking of getting a low-F harmonica. Two questions:=20 1) Are any brands better than others for this "non-standard" key?=20 2) Are they more difficult to play than standard key? E.g., I find my D = to be easier to play for low notes, but my G to be easier to play for = high notes. Thanks,=20 Oliver
