This is a tenor bass trombone (large bore) from Project Euphonium. Model number: ATBF-141G Clear lacquer finish Comes with a semi-hard case Price reduced. Like-new condition, approximately 2 months old. Consider the case as packaging for transport. As an initial defect, there is a dent of about 1cm on the upper part of the tuning slide (see photo). I was aware of this and purchased it at a slightly lower price, but in addition to that, the water key was bent, and the spit valve hole was not closed, so it didn't initially produce a sound. Also, the rubber foot was deteriorated and cracked, so it couldn't be attached. These two points have been repaired at a musical instrument store, and it is currently in a playable condition. The slide is in good condition, and the tuning slide moves without any problems. The tone is to my liking, and it sounds good. *However, the price of a new Project Euphonium trombone has been revised to be lower than the price I purchased this one for, due to the dent on the upper part of the tuning slide. I no longer want to play a trombone from this brand, so I am selling it. It has been washed, and slide grease has been applied to the tuning slide, and oil has been applied to the rotary valves. It is ready to play as soon as you apply slide cream upon arrival. Thank you for looking.
