At our workshop, which has a proven track record as a trumpet customization atelier, we have upgraded the YTR-236, one of the most successful Yamaha college model trumpets, to specifications suitable for band ensembles. This instrument rebuilds (reconstructs) the concepts of Mr. Silky, who participated in the basic design, and incorporates the same features as the high-end model (professional model YTR-637) of 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 employ similar reverse tuning are the YTR-8310Z and YTR-8330EM. ★ Rebuild Contents (Customization Overview) ■ By rebuilding the tuning slide to a reverse configuration, 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-637," a high-end model of the time. ■ The 1st slide has been rebuilt to a reverse configuration, and a ring-type thumb hook has been added. This allows for pitch control during performance and allows you to hold the instrument without gripping the valve casing, preventing the instrument's vibrations from being suppressed. ■ The movable-type 3rd slide finger ring, which is a school equipment specification, has been replaced with a fixed type. ■ The pinky hook has been replaced with a ring type. ■ The original lacquer has been removed by chemical treatment, and a scratch-brush (fine scratch) process has been applied. Coating with a sulfide film. (The sulfide film is the same reaction that causes the surface of silver products to tarnish, and the coating protects the tubing from rust.) ★ Items for Sale YTR-236 Body ★ Condition There are no noticeable dents. There is no deterioration in the piston valves or slides, and they operate normally. There are no functional problems as a wind instrument, and furthermore, the upgrade achieves a clear and light playing feel compared to current Yamaha models in the same class. ★ Due to the reverse lead pipe and unlacquered finish, this instrument has a full sound and is easy to control. It sounds very good even at volumes like pp.
