The YOB-841 features an open-bore configuration optimized to match American-style reeds. This inner bore shape is complemented by tapered tone-holes with subtle conical undercutting for a dark silky tone with a focused center.
The Model 2001, constructed with a heavier walled bore design, produces a darker and warmer tone. It also features beautiful gold posts and bands for an elegant look. Full conservatory system, silver plated keys and a third octave key come standard.
