Bernard Cassu's French jaw harp with a hard reed and a high sound. The timbre is smooth, soft, clean; when struck from itself, a weak sound is noticeable. Loudness (piercing) is not high, overtones are easily extracted. Mechanically, the jaw harp feels comfortable and behaves quite obediently with any strokes. It's thundering back.
