Designed with a new shape comparable to that of metal mouthpieces, the X.L. results in less material to suppress vibrations. The new tone chamber design yields faultless intonation and a superior altissimo register along with better control at all dynamic levels - easier to play. Critical attention has been paid to the facings. The facings are applied by a facing machine that Santy himself custom designed. This facing machine produces perfectly accurate and faultless facings every time and has a reputation for being the best facing machine in the business.
Perfect facings allow reeds to vibrate better, which results in more useable reeds.
With curves this accurate, the life of the reeds is extended dramatically. The new dynamic X.L., a product of Santy Runyon's experience producing some of the world's finest woodwind mouthpieces since 1941.
