※ This item is only listed on Mercari. 【KING 3BF】 A King trombone, a long-standing standard for professional trombones, especially in the jazz world, boasting an overwhelming global market share. This is a model based on the classic 3B, equipped with an F-attachment. The specification of a small bore (medium-small bore) with an F-attachment in a higher-end model is rare among other manufacturers. This instrument allows for both the tone and responsiveness unique to a small bore, along with the improved slide work convenience and expanded low range provided by the F-attachment. Furthermore, it is no longer in production, making it very rare to find even used. The slide, rotary valve, and tuning slides are not stuck. While it plays without issue, the exterior shows various scratches, dirt, rust, and dents, indicating significant use. Please refrain from purchasing if you are concerned about the condition. A mouthpiece is not included. Please prepare a small bore mouthpiece suitable for your intended use and playing style separately. The hard case in the photo is included. There are no problems with storage or carrying.
