I’ve been working on learning some old “Country” songs, and found out that I will have to be able to do some serious bending in order to get all the notes sometimes. But my Hohner Marine Band doesn’t seem capable of most of the bends. Maybe it’s just me but, if I try to open this harp up to inspect the reeds – are those screws or brads holding the covers in place? I seem to remember them as being brads on the Blues harps I tried back in the 70s. Don’t want to bend the covers if these are screws.
