Denis Wick SM3XR Steven Mead Ultra Large Shank Euphonium Mouthpiece - Gold Plated

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.

A large shank euphonium mouthpiece with a new rounder rim, giving increased comfort to the player, with a newly-designed inner shape and slightly reduced cup depth. Same cup diameter as the SM3U.

"Such was the success of the ultra 4XR it was inevitable that due to public demand we would produce a mouthpiece with the same design and specifics, with the number three rim. This is a powerful mouthpiece that has outstanding flexibility and big range of tone. The new comfort rim will be of great interest to many musicians. If you are used to this rim diameter, then the DW SM Ultra 3XR will meet your needs, without a doubt. With you in control it can create huge tone and presence in any band situation."
