A more compact and modified version of the MB-4, the MB-4 Baby 2 is a detachable bell flight case that fits medium-sized horns. It sports a very lean design and includes a front accessory pouch.

The bell is positioned on the top of the French horn body, inside a foam bell protector. A velcro belt keeps the instrument's body fixed and secured. Accessories can be stored in the exterior front pocket.

Measurements: 20cm x 35cm x 52cm, 3.05 kg

The case includes:

  • 2 backpack straps

  • 1 mouthpiece pouch for three mouthpieces

  • 1 foam bell divider

  • 1 foam bag with zipper for oil and accessories

  • 1 identification tag

 

Is this the right Marcus Bonna case for my horn?
