From our workshop, well-known for customizing trumpets, we have rebuilt a YAMAHA college model trumpet, the YTR-234, to function seamlessly within modern band ensembles. The YTR-234, designed by Schilke, was introduced in 1972. Its sibling, the YTR-232, designed by Schilke for the American market, was a huge hit. While it was a standard specification at the time, it lacked certain features necessary for modern brass bands and big band ensembles. We have implemented essential upgrades in our workshop to create a modern trumpet, allowing it to be used without hesitation in contemporary band ensembles. To achieve the original Schilke-type sound, we have rebuilt the tuning slide to a reverse configuration, with a level of precision that ensures compatibility with the tuning slides of the professional model YTR-637 from that era. We have also added a thumb hook to the 1st slide for precise pitch adjustment. Unfortunately, Yamaha currently only offers the Schilke-type YTR-8310Z, making our customized trumpets a valuable option. Moreover, we are offering this at a super bargain price through direct online sales. ★Customization Details ◉ Rebuilt the tuning slide to a reverse configuration, achieving the Schilke style. We paid close attention to the machining accuracy, ensuring compatibility with the tuning slides of higher-end models. ◉ Rebuilt the 1st slide to a reverse configuration and installed a thumb hook for EM use. This is an essential feature for modern ensembles. By using the 1st and 3rd slides, it is possible to produce a pedal "F". ◉ Replaced the movable finger ring on the 3rd slide with a fixed-type ring from a higher-end model. ★Condition No noticeable dents; slides and piston valves have been adjusted. No missing parts; functions normally. The lacquer coating remains at approximately 80%. While it has a worn appearance, the beauty of the lacquer is not directly related to the instrument's performance. ★Included Items ◉ Trumpet ◉ Mouthpiece ◉ Single Case
