The Meyer mouthpiece ist already a "standard" of all saxophone mouthpieces.
This meyer mouthpiece has a dark sound and good intonation over the full register of the saxophone. I only think that the highest notes (ofer f-sharp) come only with much more effort than all the other tones. I do not know how, but i have tested more than one mouthpiece and they all have this problem.
The mouthpieces comes complete with cap an ligature and you can use both.
The mouthpiece can be used for swing, bossa, blues, rock as possibly also for classic (this, however, you should choose a closer tip opening).
Whith this mouthpiece you can do nothing wrong.
