Description
The Gleichweit B11-5 Bb clarinet mouthpiece is a very open design with a long 28 mm facing – built for clarinetists who want maximum expressive freedom, a full, powerful tone, and the ability to shape phrases with precision over the widest dynamic range.
Precision-crafted on advanced CNC machinery from high-grade synthetic material, the B11-5 combines a 1.35 mm tip opening with an extended 28 mm facing. This combination gives the player exceptional control over tone colour, vibrato, and dynamics while maintaining the free, open character of a large mouthpiece.
The built-in O-ring system ensures a secure, airtight fit while protecting the instrument tenon.
Suited to advanced soloists and players who perform in large venues or with orchestral accompaniment, the B11-5 delivers the sound and presence needed to project over a full ensemble.
