My signature model is based on the S-131R. S Series guitars incorporate many details for fingerstyle players, such as the shape of the neck, and the positioning of the strings on the nut, in order to increase the playability. The size of the body is very comfortable for Japanese players. I understand this series was designed for fingerstyle players, but I also use this guitar for my studio work and backing up other musicians on the stage. Even when I tune down the strings, I can still get a rich full sound and it has become one of my main guitars. B-Band system also has a very natural sound compared with other pickup systems. Its delicate overtones and sustain fit my playing style perfectly. I think it will be my great partner for many years to come.
