If you are going to play classical music, forget about this mouthpiece. The lowest notes will shake the walls of your house! If I play it loud, the sound is edgy and powerful, very rich and has a lot (I mean: a lot!) of meat. You can push it very far and it will not complain. It is both bright and dark at the same time, the player can choose in which direction he wants to go.
You can also play it softly getting very warm breathy sound. Delicious!
Very uniform through the entire range, but I had some problems in the altissimo register, I don't know how much fault is in my (lack of) skills and how much in the mouthpiece itself.
I normally use it with Vandoren ZZ no. 2 reeds.
I can't say anything wrong about the quality, there were no inaccuracies which could be noticed with a naked eye, but I gave only 4 stars, because before buying my mouthpiece I had tested the same model bought one year earlier and they played slightly differently! It seems that either the manufacturer makes tiny changes to the design in the middle of production, or simply the products are not so precisely machined and each of them is different. I don't know, I'm just speculating...
