Excellently made mouthpiece. It was exciting to play straight away, gave me exactly the zip I wanted in my sound. If you are used to playing shallow pieces then definitely give this a go.
However, this is very shallow so I would suggest getting an intermediary piece if you currently play deeper cups. My friend who plays pieces in the 3C range struggled to even get a sound. It depends on how much lip you let inside the cup.
With that in mind, I would suggest you try a shallow piece before buying. But if it works for you, the sky is the limit!
