The Jonas draws a nice, round, and focused sound with medium-to-quick response. This bow will accompany advanced students and ambitioned amateurs to pre-professional levels of play. Features silver fittings with three-part button. The frog is made from African ebony with a mother-of-pearl inlay and the thumb leather is supple kangaroo. The smooth character of the performance is also enhanced with the use of Mongolian horsehair.
