The “OS” design incorporates a rollover baffle that transitions to a medium-large chamber. There is a moderate amount of under-cutting on the side walls.
The Drake OS Tenor Saxophone Mouthpiece is designed specifically for players who feel more comfortable playing a closer, more manageable tip opening, but; still want to establish their personal tone quality, employ a full range of dynamics and add layers of color and nuance to their sound.
This, according to Daniels, IS the “Open Secret”.
“A beautiful, centered and flexible sound is best produced with a closer tip opening… with a mouthpiece that is easy to play.”
