The Thomann TR 400 G Bb-Trumpet is a fitting choice for classical and jazz musicians. This instrument incorporates Monel valves, which eliminate sharp bends in the air passage to facilitate smooth airflow. This trumpet features a 120mm bell made from gold brass. The outer slides are made from nickel silver which are corrosive resistant. It has a stop nut on the first slide. The leadpipe made from gold brass enhances the tonal focus creating an incredibly rich tone with great warmth and presence.
