Understanding this 120/0 M setup

This Steel Duckbill configuration pairs a 120 opening with chamber 0, designated brilliant, and the M facing. Tone chamber size and baffle influence edge and brightness. More baffle gives more edge: chamber 0 is brilliant with the most edge, chamber 1 is bright, chamber 2 is round, and chamber 3 is mellow.

SMS refers to the shorter, steeper French facing. M identifies the slightly longer American facing with a flatter curve. These terms describe facing curve length rather than the mouthpiece's actual sound.

Choosing a tenor sax mouthpiece

Tip opening measures the distance between the reed tip and mouthpiece tip in thousandths of an inch. A wider opening generally allows a softer reed, while a narrower opening can help beginners achieve a clearer tone and more consistent intonation. Compare this 120 opening with your existing setup when choosing reeds.

As a reference, the designation 100/0 SMS identifies a medium-close tenor opening, brilliant chamber, and short facing. This listing is specifically for the BLS410 120/0 M configuration.
