This model is a standard model from Gottsu and is the most popular model in Japan. The tone is characterized by its deep resonance and ease of playing, allowing players to achieve their preferred sound. It aims for a nostalgic sound that doesn't get old even when played every day, the original sound of the saxophone. This model was the catalyst for Gottsu to introduce a 5-axis machining center. I studied programming from scratch to create an ebony mouthpiece that I was satisfied with and to be able to make fine adjustments to the mouthpiece myself. The VI mouthpiece is the result of that effort. Opening Size: Tip Opening (1/1000 inch = 98, mm = 2.5mm) Material: Ebony ※The material is a dark brown, high-quality ebony without additives.
