The SM Ultra baritone mouthpieces and the 'M' shank euphonium models are coming soon now.
Final testing is being done and we hope to have a definitive release/availability date imminently. The 'M' shank (medium size mouthpiece receiver) models 3 and 4, should be popular particularly in the USA where the Willson 2900 Euph is still popular.
Meanwhile sales of the Ultra euphonium mouthpieces continue to be quite incredible.
Do you have yours yet ??
