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.The new Denis Wick Ultra 4XR euphonium mouthpiece designed by Steven Mead, is a brilliant new addition to the highly popular Denis Wick Ultra range of mouthpieces. Here is what Steven says;-“The Ultra 4XR has a new rounder rim, giving increased comfort to the player, with a newly-designed inner shape and slightly reduced cup depth. The result is a new feel, almost a ‘sports’ model if you like, with enormous possibilities in the higher register, with an ease of playing and crystal clear high tones. The middle range is further energised. Perhaps it doesn’t have the same weight of sound in the lower register of the regular SM4X but the notes speak so clearly, putting added energy into each phrase. Could this be the mouthpiece to give you massive confidence in the higher range, and add valuable time to your stamina? “
