The Curry Standard Line mouthpieces are designed with a uniform rim and bite-point across different cup depths within each diameter, simplifying the choice of cups.

Moreover, there's a gradual reduction in the initial slope of the first cup, leading to a decrease in its volume and providing added support in the upper register, resulting in a gradual brightening of the sound.

The second cup, connecting the first cup to the bore, significantly influences resistance, articulation precision, and the tonal character. In the Curry Standard Line, the second cup dimensions remain consistent within each diameter, ensuring that even a relatively shallow 3Z cup shares many sound characteristics with the deeper 3C or 3B cups.
