Purchased on September 22, 2025. Used only for test playing. I prefer the metal version, so I am selling this one. Selling price: 35,200 yen. The pressure relief hole in the center releases excess reed vibration, maintaining a stable playing feel. It produces a consistent, thick sound across the entire range, and allows for flexible control of breath depending on the musical style. In addition, the independently movable rails that support the onset of the sound allow for smooth performance of detailed techniques such as staccato. The playing feel also changes depending on the position of the attachment, so please adjust it to your preference. Three features: ① Pure tone that combines warmth and brilliance ② Stable resonance from p to f, and from low to high notes ③ Flexibility to enjoy a variety of musical genres
