Very neatly made khomus with good dynamics. The knee of the tongue is not the most stable and generates a number of distinctive extraneous sounds, especially strong with the back stroke. Sensitivity is average - with weak strokes, the sound is quiet and quite inexpressive, but it comes to life with increasing amplitude of the tongue, it becomes colorful and saturated without adding dirt. A good jaw harp, but only for inwards strokes.
