This is a large fiberglass case designed to hold a tenor trombone and a bass trombone. It's made by Marcus Bonna in Brazil. We stock these in black nylon, but a myriad of colors in both nylon and leather are available by special order. Custom cases are usually made in 60-90 days.
Shown in the photos are a Getzen 3062AF Custom bass trombone and a Bach 42AF tenor trombone. These were easy to fit together in this case, and we think nearly all similar trombones should fit without extra effort or headaches.
The cover is attached to the fiberglass shell with Velcro type material, and it is easily removed if cleaning, repair or replacement is necessary. The cover has attachment points for a shoulder strap, double backpack straps and an external sheet music pocket that is also attached with zippers for easy removal. The interior has storage space for small accessories.
Accessories included: shoulder strap, backpack straps, double mo8uthpiece pouch, ID tag, extra foam blocks, sheet music pocket with loops for a trombone stand.
Despite tough fiberglass construction, Mr. Bonna recommends that you consider this case to be hand luggage. If you entrust $10000 worth of trombones to an airline baggage handling system, all bets are off. We're not saying it can't be done, but thorough packing with extra materials would be necessary, and success is not guaranteed.
This is one of the largest cases we carry, and though Marcus Bonna cases are know for their light weight, this case is no light weight wonder. It's large, bulky, and fairly weighty. But given that, it's very useful if you need to carry two large trombones with you. A traditional road case would weigh several times as much, and a Cronkhite case, though smaller and lighter, does not offer the full fiberglass shell of the Bonna.
