Hi Quetscher,
This clarinet-type mouthpiece is what I have been dreaming about along with sax- and oboe-type mouth pieces. I have yet to experiment with any of these mouthpieces primarily because I must play with a short tube and so I need a mouthpiece that will not slide out of my mouth. The only solution I have come up with is to put notches in these mouth pieces so I can hold them between my teeth. Hopefully soon I will find a woodwind shop and an expert who can help me find and modify a mouthpiece.
Regards,
Lowboy
