The BF-303 Bellfront Baritone from the house of Thomann incorporates three Périnet valves for the elimination of sharp bends in the wind passage. In this way, the valves allow for accurate pitch adjustments. Such a set-up helps maintain smooth airflow. This instrument exhibits a bore size of 14.5mm and a bell size of 280mm. The body of the instrument is constructed out of brass, an alloy widely used for its exceptional corrosive resistance. The clear lacquered finish adds radiance to the overall design. The BF-303 is accompanied by a protective case for easy portability.
