MB5ST detachable bell French Horn Case

The MB5ST is an original design by Marcus Bonna. Made by hand in a 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, and room for a small folding music stand. The MB5ST has a zipper enclosure and a soft cloth quilted interior over forgiving foam. The shell is made of molded fiberglass (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, 1 straight mute and 1 stopping mute, or a small folding music stand and a mute of choice in the lid.

New to the MB5ST line up includes a carbon fiber base structure.

This optional add on is 300g lighter than the standard fiberglass shell. The carbon fiber is a bit stiffer in feel and the 300 grams is noticeably lighter.
