3. T 280 is a 2.80 mm tip opening (110/00”) equivalent to the traditional “8” opening. Combined with a medium short facing length and a progressive facing curve. This is the “universal” mouthpiece: very stable, centered pitch, small enough to be playable by good amateurs and students, big enough to put real amount of air and be playable by professionals. Lots of projection with bottom on the attack of the note, very precise. Virtually every reeds fit, from 1 1/2 to 5.
    
4. T 285 is a 2.85 mm tip opening (112/00”) equivalent to the traditional “8/8*” opening. Combined with a medium long facing length and a soft facing curve. Due to the longer facing curve, it brings more resistance and takes more air.(This make it feel “bigger”) The soft curve gives it a lot of flexibility. This is the best mouthpiece for the professional player that needs to use all possibilities of dynamics, sound colors and range in one mouthpiece., without having to struggle too hard on a real big mouthpiece. Best fit with 2 1/2 to 4 reeds.
    
5. T 315 is a 3.15 mm tip opening (124/00”) equivalent to the traditional “9*” opening. Combined with a medium long facing length and a progressive facing curve. Very well balanced and efficient, it keeps a well centered pitch with flexibility, lot of projection and a big fat low range “à la Ben Webster”. For the player who likes to blow a lot of air without loosing control. Best fit with 2 to 4 reeds.
