Never thought I could find a mouthpiece to better Vandoren, but my Yamaha 4CM greatly outperforms my new Vd A15. It has a big rounded sound with a dark quality, with dynamics ranging from a sweet piano to a menacing fortissimo! It feels like it was made for my Yamaha 62 alto - possible because it was!
A brilliant mouthpiece for a knockdown price.
No, I don't work for Yamaha!
