'A great new composite material.... inspired by finding a modern material that resonates like wood, with absolute consistency and more focus. A new design with beautifully mixed polished and sanded (matte) surfaces, with an inwards curve at the junction between the beak and the body of the mouthpiece and at the junction between shank and body.'

I think this is a corker of a mouthpiece! I found an enormous potential for expression and control available - the sound is very round and centred but there is an enormous potential to play with a very big dynamic range. The response is also excellent and it seems to be very economical with the usage of air. Definitely a mouthpiece to be considered by the serious baritone player!' 

PLEASE NOTE: Supplied without ligature- for use with tenor hard rubber sized ligatures 

Tip Openings

B285 is a 2.85 mm tip opening (112/00”) equivalent to the traditional “7” opening. Combined with a medium facing length and a soft facing curve. Great flexibility with a lot of projection and immediate response. 

B305 is a 3.05 mm tip opening (120/00”) 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, centred 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. 

B325 is a 3.25 mm tip opening (128/00”) equivalent to the traditional “8*/9” 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.
