★★★ High-Quality YAMAHA Made in Japan Atelier Upgrade ★★★ At our workshop, which has a proven track record as a trumpet customization atelier, we have customized the YAMAHA college model trumpet YTR-233 to be seamlessly integrated into modern band ensembles (orchestras), making it suitable for wind bands. We have rebuilt the basic design of this instrument based on the concept of "Schilke," a top trumpet manufacturer, and incorporated specifications similar to the then-existing Schilke clone instruments (pro model YTR-636). We have fully upgraded the now-difficult-to-obtain M-bore instrument. It is also ideal for lead playing in wind bands and big bands. You can obtain a reverse tuning specification, often found in high-end instruments, at a very reasonable price. This is perfect for those looking for instruments for their wind band using their Mercari sales. The quality as a performance instrument is overwhelmingly different from new Asian-made imported instruments. ★ Customization Overview ◉ By rebuilding the tuning slide to a reverse configuration, we have achieved the smooth and light playing feel unique to the Schilke type, reducing stress even during long hours of playing. We have also paid close attention to processing accuracy, and it is compatible with the tuning slide of the high-end model "pro model YTR-636." ◉ We rebuilt the 1st slide to a reverse configuration and installed a saddle-type thumb hook. This allows for pitch control during performance and enables the player to reach pedal "F." Holding the instrument without gripping the valve casing prevents the instrument's vibrations from being suppressed. ◉ By replacing the movable-type finger ring on the 3rd slide with a fixed type for high-end models, we have eliminated the image of school equipment and achieved tight operability. ◉ The 3rd slide stopper can now accommodate the current YAMAHA screw instead of the thin screw of the time (EM parts installed) ※ Replacement parts are genuine YAMAHA products. ★ Condition The lacquer remains at approximately 95% or more. There are no noticeable dents. ★ Items for Sale Body, mouthpiece, hard case (new 3-way) ★ Options Adding a brace to increase resistance in the playing feel (+2,000 yen) ★ Instrument Trading Trumpet Custom Workshop
