The 10K Series mouthpieces are the culmination of 30 years of experience as a mouthpiece maker and 10,000 handcrafted professional mouthpieces sold.  These mouthpieces are computer machined from excellent German rod rubber. I have designed these mouthpieces for beauty of sound, response and excellent intonation. The 10K series mouthpieces are expertly manufactured for me by master craftsman Wesley Rice of Rice Clarinet Works

All Fobes professional mouthpieces are designed to play at A440. We sell Clark Fobes Eb clarinet barrels in sizes ranging from 41mm - 43.5mm in .5mm increments if you want to lower or raise the pitch.
