Sepia Tone VI

Sepia Tone VI is the standard Gottsu model, and the most popular in Japan. The “VI” label stands for “Vintage”; it is only coincidentally also the roman numeral VI.  The features of this model are its dark, focused sound and ease of blowing. With the Gottsu Sepia Tone VI, you are free to make your own sound.  


I made this model to give musicians nostalgia while playing it.  The style is designed to reflect the vintage jazz era.  Although other styles and sounds are fun to explore for a while, this mouthpiece will be the favorite that you always return to. 

The reason I decided to implement 5-axis center machining at Gottsu was because of this model.  I really wanted to make the best hard-rubber mouthpiece in the world, so I spent many hours studying the programming in order to fix errors by myself.  That is how I started to create this Sepia Tone VI model.
