The B45, created in 1968 by Bernard Van
Doren, came as a revelation for many
clarinettists. It was rapidly adopted by the
leading clarinet players of the time. This
mouthpiece became another standard of
professional comparison, thanks to its
innovative features:
- A wider tip opening than the 5RV
- A medium length facing
Result: great evenness, with a smooth
and pure tone and easy articulation
