Thank you for viewing. This trombone was used when I was in a symphony orchestra for about 6 years. I kept it with the intention of joining an orchestra again someday, but since I don't think I'll have the opportunity to play it anymore, I'd like to pass it on to someone who can use it. The YAMAHA YSL-648 is a professional model trombone with a very deep and rich tone, and it's still a popular instrument today. Also, I won a gold medal when I used this for a brass quartet competition. For the listing, I had it maintained and cleaned at a musical instrument store for 40,000 yen, so it works very well. At the time, I bumped it and dented the bell, but that has also been repaired. Consumable parts have also been replaced with new ones. In addition, there are some small scratches. There are also light stains on the case cloth. The mouthpiece is discolored, so I recommend purchasing a new one that suits you. Cleaning cloths and lacquer polish are not included. Please check the condition in the photos. Everything in the photos is included. 【Manufacturer】 YAMAHA 【Item】 Tenor Bass Trombone 【Model Number】 YSL-648 【Key】 B♭/F 【Bell Diameter】 21.3cm 【Mouthpiece】 VINCENT BACH CORP. 6 1/2AL For large shank 【Case】 YAMAHA Genuine Hard Case 《Accessories》 Instruction Manual 《Maintenance List》 ・Slide adjustment ・Water key cork replacement ・Water key spring replacement ・Bump rubber replacement ・Stop band felt replacement ・Rotary adjustment ・Rotary string replacement ・Internal tube cleaning ・Dent repair ※In addition, the repair completion report states, "Although cleaning was performed, the smell of mold remained." I moved the slide and sniffed the inside of the tube, but it wasn't a strong smell, just a slight smell characteristic of wind instruments. However, I think there may be individual differences in how it is perceived, so please refrain from purchasing if you are sensitive. Since this is my first time shipping a musical instrument, it will take 2-3 days to ship. I plan to use a careful shipping company. I will take great care to protect it from impact and pack it carefully. ※Please feel free to ask if you have any questions. ※Please refrain from price negotiations.
