Berg Larsen has a great history in producing mouthpieces, especially for the bright, assertive sound. This metal mouthpiece offers exatly that big, funky sound with a lot of overtones and a great response. It responds very well in every register and you can blow it from pianissimo to fortissimo without struggling with abrupt ending notes.
The only thing you have to consider is that there is a quite high spreading in between different mouthpieces, even of the same tip opening und facing curve. So if you are planning to get a Berg Larsen, make sure to test as many of the same model as you can.
