Used King 3BF trombone. I used this for a few gigs but don’t play it much anymore, so I’m hoping someone else gets good use out of it. Plays great and is in good condition. Please refer to the pictures. Slide: Clean inners with no wear. Slide moves freely with a slight amount of hesitation in 7th position. Some lacquer wear at contact points and on one slide leg. Water key is airtight and rubber is in good condition. F attachment: Mechanical linkage. Makes a slight amount of noise but pulls easily and has a short throw.Bell: Great condition, a couple very small dents.Comes with a rectangular black case with blue velvet interior and Bach 6 1/2 AL mouthpiece. Stand in pictures is not included.
