The Faxx mouthpieces were developed as facsimiles of the more common designs at more economical prices. Only the most popular sizes have been reproduced to guarantee the lowest prices possible for these quality mouthpieces.
Similar to the Bach equivalent sizes, the 5C mouthpiece is a medium cup mouthpiece with a soft edge and brilliant tonal response. Fit for all-around playing and recommended for advancing players or players who require a slightly smaller cup diameter than the 3C.
The cup diameter of the Bach 5C is smaller than the Bach 3C, but larger than Bach 7C.
