Model K Mouthpiece RCW

The Chicago Kaspar mouthpiece has a legendary reputation among clarinetists — powerful, brilliant, and capable of cutting through a full orchestra. Rice Clarinet Works used the best examples they could find as the foundation for the Model K, studying what made those pieces work and building on that foundation with their own improvements and manufacturing precision.

RCW collaborated with master mouthpiece maker and principal clarinet of the South Dakota Symphony Chris Hill to help develop the designs — a partnership that brings serious professional input to every model in the lineup. The result is a mouthpiece with a powerful, brilliant tone that projects with authority in ensemble and orchestral settings, built to RCW's exacting standards rather than simply reproducing a vintage piece.

Every Model K is CNC machined in-house, then hand-faced, sanded, and play-tested over the course of several days. That finishing process is what separates it from mouthpieces that come off a machine and go straight into a box. Each piece is individually worked until its characteristics are fully developed and confirmed by a real player.

The machined hard rubber blank is more dense than molded alternatives — the material stays cool during cutting rather than heating under pressure, which produces a denser, more resonant result that plays better and lasts longer.
