The handmade Marcus Bonna bass trombone case consists of a fiberglass shell with a durable replaceable nylon cover. The case is a standard length with an extremely compact, contoured design. This is one of the most protective cases on the market and is use by many of the world's top professionals. It is the most compact bass trombone case designs we've seen, fully three inches narrower at the bell flare than anything else. Outwardly, with its 11-inch/28cm wide bell flare, it could pass for a tenor case. It might even fit in an overhead compartment on some larger aircraft, no small feat for a bass trombone case. The interior is well appointed and fits everything, from a single rotor to a dual thayer horn.
Modelo F - This is the "Modelo F" variant of Bonna's traditional bass case (our item 100572). It is the same in nearly all regards with the exception that the lower hinged section is about a half inch (1.25cm) deeper to accommodate some models with wider valve sections. The weight is only slightly higher by about 1/4 pound (0.12 kg) as a result. Otherwise it's the same case as the standard 100572. -cdp
