Trumpet Customization Atelier "Inst Trading" upgrades high-quality college model trumpets, originally produced by YAMAHA under the supervision of "Schilke," the founder of a high-end American trumpet maker until the 1980s, through rebuilding. We implement specifications suitable for modern band ensembles (orchestras) and offer them at reasonable prices. This YTR-234 is a reliable instrument carefully manufactured at YAMAHA's domestic factory. Furthermore, we have fully upgraded it to a modern trumpet at our workshop, making it ideal for brass bands and big band ensembles. ★Customization Points ・By rebuilding the tuning slide to a reverse configuration, we achieve a smooth and light playing feel unique to the silky type, reducing stress even during long playing sessions. We are also particular about processing accuracy, ensuring compatibility with the tuning slide of the "Pro Model YTR-637," an advanced model. ・We rebuilt the 1st slide to a reverse configuration and installed a saddle-type thumb hook (YAMAHA genuine parts). This allows for pitch control during performance. ・By replacing the movable finger ring of the 3rd slide with a fixed type (YAMAHA genuine parts) for advanced models, we eliminate the image of school equipment and provide tight operability. ★We offer optional customizations. ★Condition This instrument has a lacquer finish remaining at over 90%, and there is no sign of use in the tubing or valves. Dents and scratches are only noticeable at close range. However, some solder removal marks remain due to the rebuilding process, which is the heart of the trumpet. ★Items for Sale Body, mouthpiece, genuine case ★Optional Orders Case/Mouthpiece: Not needed - ¥2,000 Add a brace to the tuning slide: +¥2,000 (YAMAHA genuine parts) Replace with a ring-type thumb hook: +¥1,500 (YAMAHA genuine parts) Replace with a pinky hook for advanced models: +¥2,000 (YAMAHA genuine parts) Current YAMAHA genuine slide stopper: +¥1,000 (YAMAHA genuine parts) ※Please specify in the comment section.
