This medium shank euphonium mouthpiece is the perfect blend of resistance and air flow.
Large cup diameter and barrel backbore gives a big, open sound.
The Steven Mead Ultra X series is for players looking for a sound that has more brilliance than the standard Ultra Series or classic Steven Mead Series. The cup has been rounded to a more defined bowl shape which adds more brilliance to the tone and provides better upper register response. The rim has been altered to have a slightly sharper inner edge which increases articulation response and accuracy.
