Used Courtois 420MBO tenor trombone, a popular model. It's in excellent condition. 【Condition】 The exterior is in like-new condition. The slide and rotary valve move without issue. The case is lightweight, compact, and can be carried as a backpack. The surface material (fabric) is somewhat delicate, so there are a few scuffs. A Courtois mouthpiece and a Bach 6-1/2M mouthpiece are included. 【Features/Other】 In my personal opinion, this instrument produces a solid, full-bodied sound in the mid and low registers, and a bright, vibrant tone in the high register, typical of Courtois. The slide is lightweight and easy to operate. The bell section has a bit of weight to it. I think this is an instrument that can be used in a wide variety of situations. It's in excellent condition, so if you're interested, don't hesitate. 【Included Items】 Case, mouthpiece 【Other】 Non-smoking environment. No pets.
