The CHI Brass R Helleberg began as a design for one of our most prominent orchestra tubists.  They loved the sound of our JS Helleberg but wished for a heavyweight mouthpiece with a smaller inner diameter while retaining the Sear style rim and the tonal characteristics of a big burly sound  of our JS Helleberg Model.

The R Helleberg retains the Sear Style Rim, shank, throat and back bore of our popular JS model with a reduced inner diameter and heavyweight shell.
