After suffering an accident in 1990 that seriously injured his back, he designed a new case for himself. This case was lighter, more compact, and featured a brand new design to facilitate the transportation of his instrument, as the cases available on the market were too big and heavy. To his surprise, the case was so successful among his orchestra colleagues that, in a short time, these same colleagues had new cases made in fiberglass by Marcus Bonna himself.\u003c\/p\u003e\n\n\u003cp\u003eIn 1991, the Munich Philharmonic Orchestra had a performance in São Paulo. When the horn players from this orchestra saw the new horn case model, they were very impressed and interested in acquiring one. As a result, to start fulfilling orders both in Brazil and abroad, the MB company was founded in 1991. Today, the company has 45 employees at its headquarters in Bragança Paulista, 80 km from São Paulo.\u003c\/p\u003e\n\n\u003cp\u003eIn addition to the production and management sections, the company also has a canteen, a playroom, and an auditorium with a grand piano for classes and chamber music. MB exports about 480 cases a month to more than 25 countries. All the cases and mutes are handmade. The case models are exclusive, with some protected by patents, and all are designed and developed by Marcus Bonna himself.\u003c\/p\u003e\n\n\u003cp\u003eThese cases are highly customizable and aimed to provide the best protection possible, please give our Band Sales Department a call at: (301) 946-8808 for more information and to make sure we are getting you set up with the correct case.\u003c\/p\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\n\n\u003c\/p\u003e\u003ch4\u003eSPECIFICATIONS\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInstrument Compatibility: Tenor trombone (up to 8.5-inch bell) and bass trombone (up to 10.5-inch bell)\u003c\/li\u003e\n  \u003cli\u003eValve Type Compatibility: Fits with or without rotary valves\u003c\/li\u003e\n  \u003cli\u003eSlide Storage: Side compartment\u003c\/li\u003e\n  \u003cli\u003eInternal Protection: Foam divider between instruments\u003c\/li\u003e\n  \u003cli\u003eAccessory Storage: Internal space and detachable sheet music bag\u003c\/li\u003e\n  \u003cli\u003eTrombone Stand Attachment: Yes, on sheet music bag\u003c\/li\u003e\n  \u003cli\u003eBackpack Straps: 2 included\u003c\/li\u003e\n  \u003cli\u003eShoulder Strap: 1 included\u003c\/li\u003e\n  \u003cli\u003eMouthpiece Pouch: Holds 3 mouthpieces\u003c\/li\u003e\n  \u003cli\u003eIdentification Tag: Included\u003c\/li\u003e\n  \u003cli\u003eMade in Brazil\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cbr\u003e\n\n\n\nManufacturer: Marcus Bonna\u003cbr\u003eModel: MB-TTBN\u0026amp;BTBN-NY1\u003cbr\u003eSKU: I463049-N-0-WHXC\u003cbr\u003eUPC: 751320471178\u003cbr\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cb\u003eWe are Chuck Levin's Washington Music Center\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eSince 1958, Chuck Levin’s Washington Music Center has been the trusted destination for musicians and audio professionals across Maryland, Virginia, and Washington, D.C.
