The S43HDL-F Faddis Model trumpet was designed with cooperation with legendary jazz artist, musician, composer, educator and conductor Jon Faddis. Created around the HD series valve section that creates a heavier center for the trumpet, the S43HDL-F has a HD yellow brass tunable bell with a #3 taper that offers more resonance and has a more open feeling, especially in the upper register. This Faddis-model trumpet also features no nibs on the second valve slide, no main tuning slide water key, heavy valve caps and adjustable tuning bell brace.
