Thank you for viewing. Used item. The pistons and slides are not stuck, and all parts function well. The inside of the tubing has been cleaned, basic operation has been confirmed, and a simple play test has been performed, so you can enjoy playing it immediately. In my subjective opinion, the exterior has a deep, well-used feel, and the polished brass shines with a profound presence. 【Important】 Unlacquered. ■ The appeal of unlacquered (ChatGPT) ① The sound of the brass itself, which cannot be experienced with plating or lacquer. The tone is soft and tends to be rounder than with lacquer. ② The unique vintage feel that changes with the oxidation film as you use it is attractive. You can easily restore the original shine by polishing with Piccard liquid, etc. ③ A unique tone with a strong presence in jazz and solo performances. ■ About YTR-233 (ChatGPT) A standard model for beginners to intermediate players manufactured in Japan in the early 1970s. It features a simple and highly practical design. It is an excellent trumpet as an entry-level instrument in terms of "ease of playing," "durability," and "balance of sound quality." ■ Condition No missing parts, all parts function well. There are signs of use such as minor scratches, dirt, and dents. There is a slight bend in the bell.
