This is a tenor bass trombone (large bore) from Project Euphonium. Model number: ATBF-141G Clear lacquer finish Comes with a semi-hard case This item is like new, having been purchased about two months ago. 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 discounted price, but in addition to that, the water key was bent, and the spit valve hole was not closed, so it didn't make a sound initially. 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 now in a playable condition. There are some repair marks on the water key. 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, due to the dent on the upper part of the tuning slide, the new price of the Project Euphonium trombone has been revised to be lower than the price I purchased it for. I no longer want to play a trombone from this brand, so I am putting it up for sale. I have washed it, applied grease to the tuning slide, and oiled the rotary valves. It is ready to play as soon as you apply slide cream upon arrival. Thank you for looking.
