That's an interesting idea. I wouldn't know how to describe the sound well enough to produce a scaled-up version for bari, but it may be worth expoloring.not yet, but they are not likely to develop something for a market that small any time soon.
If you like the idea, why don't you get in touch with SYOS and see if the can produce you ( they do 3D mouthpieces) which will take the curve and design to the size you need?
They are expert acoustitians and may be interested, their production method allows for a small time production.
I only have experience with the scroll shank Larry Teal and Soloist/Soloist Style pieces. The Soloist/Style models have a horseshoe-shaped chamber, the LTs are round. I actually find the LT and the Concept to be somewhat similar, but the Concept seems to have a thinner, flatter beak, a smaller tip, and longer facing. Sound-wise I find the Concept just a little fuller and more complex, but only trying one of each, the differences could be attributed to the inherent inconsistencies from piece to piece.What's the difference between the Concept and other Selmer pieces like the Super Session, Spirit, and Soloist? The outside shapes are different but internally they all seem very similar to me- just curious?
I've wanted to try the Spirit (Meyer-ish) and the SD20 (original round chamber Soloist, discontinued?), but haven't had the chance yet. Still haven't tried a Super Session yet, either.
