The STOMVI idea –which revolutionised the concept of the mouthpiece available until now– is the definitive answer enabling all instrumentalists to solve their own problems with a precise method.

The rim, in contact with the player’s lips and therefore an essential part of the instrument, must not be changed unless there is a good reason for doing so. However, the other parts of the unit- the cup, backbore, materials employed, weights, grain, etc, can be changed at will to obtain the desired results.

Stomvi also offers a chart to compare mouthpiece sizes: [See chart]
