I was searching for a open tip mouthpiece so I decided to try glass.
After B45 p88,B40,M30lyre,Cl4 and Cl5 I find what i was looking for.
I know that mouthpieces are a personal opinion but I must say that this is a very good mouthpiece.
Better response than any of the others I mentioned,compact sound,not so easy articulation but thats maybe a good thing and yeah!glass does his work!
thanks
