Yamaha YAH-803S NEO Althorn

The two-piece yellow brass bell features a larger diameter to deliver a wider dynamic range.

The first branch features a new design that offers improved pitch and greater tone colour. The main tuning slide is designed with a new taper and wider bow that produces greater tone colour, a freer feel, more accurate pitch, and greater dynamic range.

A new, heavier valve casing design produces a richer, more authoritative tone.

The mouthpiece receiver and brace design produces a moderate amount of resistance and thicker sound when playing, delivering greater projection and expressiveness.
