Add a note to encourage purchase

The MB5ST High Compact is an intelligent design based on the MB5 series for detachable bell french horn cases by Marcus Bonna. Designed for a more compact and versatile lifestyle, this model can fit a number of horns. Upgrades are now available to have the base structure made out of carbon fiber instead of fiberglass. This is a stiffer material and is 300g less in weight.

The MB5ST series are an original design by Marcus Bonna. Made by hand in Brazil, Marcus Bonna cases are among the most popular by horn players of all levels. The MB5ST rests the bell at a slight angle over the corpus providing less overall thickness of the case compared to the MB1 model. Included are: padded backpack straps, shoulder strap, mouthpiece pouch. The MB5ST has a zipper enclosure and a soft cloth interior over forgiving foam. The shell is made of molded fiberglass which is standard. A small triangular shaped accessory pouch is inside. Outside you will find a small zipper music pouch on the back, and on the top is another triangular shaped zipper pouch.  The MB5ST case includes the space to secure 2 straight mutes, or 1 straight mute and 1 stopping mute in the lid. 

The MB5ST High Compact has the same interior space as the standard MB5ST for the corpus of the horn. However, the height is tall enough to fit taller bell flares such as those from Yamaha.

The MB5ST High Compact with wheels features a retractable handle that is easily removed by zippers off of the flat back of the case. Once removed, there is space inside the case should you want to store the handle and carry the case as a backpack or over your shoulder like a briefcase. The roller function is smooth and quiet. The retractable handle is compact and durable. When the handle is being used, you can easily travel with 2 mutes inside the case. Outside is a removable sheet music pouch large enough to carry the music you are currently working on.


22.5cm x 35cm x 51cm – Case for some horns with detachable bell, 1 straight mute and 1 stopped mute.
