Designed by renowned instrument technician Jack Onque and trumpeter Richard Boulger, the JORB offers all brass players a new practice tool that will support the development of one's embouchure and overall 'chops' strength'. The JORB and its unique, spring-loaded, cushioned rim will help players to develop a stronger lip vibration and aperture strength, while also serving as a means to help instill a relaxed, steady, air stream. All this promises to give brass players a pronounced improvement in their overall playing. As a teaching tool, The JORB allows students and teachers to clearly view the aperture size and how ones embouchure is responding. Made in the USA
