This is a lightweight fiberglass case for bass trombones with a screw bell flare. The case is made in Brazil by Marcus Bonna, and fits a single or double valve bass trombone with a bell up to 10.5" (29cm) diameter. The outer cover is easily removed and replaced if it ever needs repair, cleaning, or replacement. The inside features modular foam blocks to customize the fit to your instrument. The 12x16" (30x40cm) music pocket attaches with zippers and is easily removable. The pocket features loops to hold a trombone stand. There is a small storage compartment in the small end of the case, and a small pouch in the middle that may hold extra leadpipes.
The slide is stowed at the bottom with a velcro strap. On top lies the body of the trombone separated from the slide by a foam partition. The bell gets attached to the lid of the case with an elastic belt. This assembly allows the case to be very small and very light. There is space for accessories in the exterior pocket and detachable sheet music bag. A trombone stand can be attached to the sheet music bag.
