※ Regarding price negotiations, I have described them in my profile. Please check it in advance. This is a YAMAHA tenor trombone, model YSL2510. A small shank mouthpiece can be used. In addition to the instrument itself, the following are included: ・Mouthpiece (JUPITER 12C) ・Hard case (for transportation) ・Cleaning rod This trombone was called the "College Model" and was manufactured between 1984 and 1994. It is considered to be an entry-level to intermediate-level instrument, and it is easy to play and produce sound even with a light breath. Because of the yellow brass bell, it has a clear tone, which I think is especially good for pop music, jazz, etc. The College Model is an instrument targeted at students and beginners, and I think it is one of the easiest models to play. The narrow slide makes it easy to hold even for smaller people, and I think it's also good for those who are just starting to play the trombone. There are scratches, dents, discoloration, and lacquer wear, and it shows signs of use, but it is fully playable. The slide also has some plating wear on the inner tubes, but it moves smoothly and slides to the 7th position by its own weight. When listing, I have cleaned the inside of the tubes with a cleaner and neutral detergent. In addition, the slide felt, water key cork, and bumper rubber have been replaced because they were deteriorated. After cleaning, I have greased it and checked the sound, so you can use it immediately. After the check, I have wiped the slide to protect the inner tubes. (If you wish to have slide oil applied, please contact me after purchase.) I don't think there are any problems with playing, but it is a used item, so please judge from the photos and consider it. Please note that it is also for sale elsewhere. We will give priority to the person who purchases it first, so please be aware of this.
