The Steven Mead Ultra series is the newest evolution in euphonium mouthpieces. The outer shape has been changed to add more mass, which increases projection. An evolved cup shape combines the best elements of a funnel shape and bowl shape to produce a classic euphonium/baritone sound with better support and response in the upper registers. These mouthpieces have only been on the market for a few months. For more details, please see the Euphonium Store's website, the seller. I accidentally ordered two. This is a completely unopened item for sale. First come, first served. Of course, it's in extremely excellent condition. I haven't even touched it. I don't think it's sold in Japan yet. 【No price reduction】Please understand. Thank you.
