The Suzuki Bluesmaster is a 10-hole diatonic harp. It has thin phosphor bronze reeds and a plastic comb. The stainless steel reed plates and covers give it a nice appearance, and they also help to give it a pleasant sound. In fact, although it's an affordable diatonic, it can really be used by beginners or professional musicians. It doesn't take much air to play each note, which means that it is useful in concert settings, as well as a nice learning tool for novice players. Another reason that this harp is so easy to play is that the comb and the cover plate line up perfectly. Other models have combs and cover plates that are different widths.
