Light plastic mouthpiece for easy upper register. The response is similar to other lead mouthpieces, the feeling on the lips is quite different, mostly because it has less grip than a metal mouthpiece.
The projection is great, the overall volume is a little lower than a metal mouthpiece.
The Scream model has an almost flat cup, granting fast and easy response, really bright tone and great projection, the low register is a little brittle and out of focus, as any lead mouthpiece.
The plastic material makes it more comfortable to play in cold enviroments like outdoors in the winter.
