Thank you for viewing. This is a tenor-bass trombone made by Kaerntner. My daughter purchased this for self-practice at home when she was in the brass band club. Now that she has retired from the club and no longer uses it, I would like to offer it to those who are starting to play an instrument or are looking for one for practice at home. 【F-Attachment Lever】 Unlike regular trombones, this model has an "F-attachment lever" operated by the thumb. By using the lever, you can change the pitch without extending your arm too far, which is an advantage for those who are small or whose arms are not long enough, such as children. It was also useful for practicing at home. 【Condition of the Product】 Playing: I have tested the sound for the listing and confirmed that it can be played without any problems. Operation: The lever, slide, and tuning slides all move smoothly. Appearance: Since it was for home use, there is no major damage, and it is generally clean with a golden shine. There are slight dullness and minor rust spots (see photos) inside the bell and around the lever due to use, but they do not affect the performance. Case: The included hard case has been partially damaged, so it has been repaired with tape. There is no problem with carrying it, but it is priced lower than the quality of the instrument itself. Please consider it for shipping purposes. 【Accessories】 Body (tenor-bass) Mouthpiece Hard case (with repairs) Cleaning rod Although it is a large item, I will carefully pack it with bubble wrap and ship it promptly. This was my daughter's cherished instrument, so I would be happy if someone else could make good use of it. Immediate purchase is OK. Thank you.
