The Royal Global COHLER clarinet bell is an original collaboration between Royal Global and American clarinetist Jonathan Cohler in 2006.

• Originally, each bell was finished by hand in Boston for several years. Now, based on a spectacular master model, the COHLER bell is produced in the Royal Global factory using CNC technology for the highest level of precision and consistency.
• This bell has more wood than most traditional bells, and a significantly redesigned inner bore with patented inner extension that gives more resonance to the lower notes and an overall more powerful, colorful sound.
