CroxBelt Designer


Hello - I'm an architect, designer and musician, playing jazz piano, tuba and sousaphone. More than 30 years ago I started to develop a strap for my sousaphone to carry it on both shoulders, with my back and pelvin. The CROXBELT strap now has become a really helpful tool for all tuba and sousaphone players. Enjoy the lightness of wearing your instrument with this strap.

CROXBELT II/40, II/50, III/50 and WAIXBELT which can be used also for accordions!

CroxBelt Designer

Ich bin Architekt und Designer und spiele Jazz-Piano, Tuba und Sousaphon. Vor mehr als 30 Jahren habe ich mit der Entwicklung eines Tragsystems für Tuba und Sousaphon begonnen, welches das Gewicht auf beide Schultern, den Rücken und das Becken verteilt. Vor ein paar Jahren ist daraus ein eigenständiges Produkt entstanden: CROXBELT II/40, II/50, III/50 und WAIXBELT, der ebenfalls für Akkordeons verwendet werden kann.

Viel Spass beim Spielen mit dem CROXBELT!

by the way ....

the WaiXbelt is a belt which goes around your waist and helps - in combination with the CroXbelt II-40 or II/50 - to carry your tuba or sousapohne with your hips as well. It can be used as a single strap for accordions as well  !!!

what makes the CROXBELT extraordinary ?   

it's not only the CroXbelt around your body ...

it's the MiniStrap or MaxiStrap which fits a     ring on the tuba or the sousaphone          ;-)  there where you always wanted to hook in !
