At our workshop, which has a proven track record as a trumpet customization atelier, we have upgraded the YTR-2320E, a long-selling standard model trumpet from YAMAHA, to modern specifications suitable for band ensembles. We have also adopted a cool finish with a scratch-brush and sulfide film coating, which is a global trend in custom trumpets. All hooks have been replaced with ring types, achieving a unified sound. This instrument rebuilds (reconstructs) the concept of Mr. Silky, who participated in the basic design, and incorporates the same functions as the high-end model (professional model YTR-6320) at the time. This is the best option, allowing you to obtain a reverse tuning specification, often found in high-end instruments, at a very reasonable price. YAMAHA's current models that use similar reverse tuning are the YTR-8310Z and YTR-8330EM. ★Rebuild Contents (Customization Overview) ■ By rebuilding the tuning slide to reverse, we have achieved the smooth and light playing feel unique to the Silky type, reducing stress even during long hours of playing. We have also paid close attention to processing accuracy, ensuring compatibility with the tuning slide of the "professional model YTR-6320," a high-end model at the time. ■ The saddle-type thumb hook on the 1st slide has been replaced with a ring type. ■ The movable finger ring on the 3rd slide, which is a school equipment specification, has been replaced with a fixed type. ■ The pinky hook has been replaced with a ring type. This eliminates micro-vibrations at the ends of the parts. ■ The original lacquer has been removed by chemical treatment, and scratch-brush processing (fine scratches) has been applied. Sulfide film coating. ★Items for Sale Main body ★Condition There are no noticeable dents. There is no deterioration in the piston valves or slides, and they operate normally.
