Description
The Gleichweit B10-4 Bb clarinet mouthpiece is an open Bb clarinet mouthpiece with a long 28 mm facing – designed for players who want maximum tonal flexibility, a full singing sound, and the ability to shape dynamics across the widest possible range.
Machined from high-grade synthetic material on advanced CNC equipment, the B10-4 pairs a 1.27 mm tip opening with a generous 28 mm facing. The long facing rewards a player with a developed embouchure, enabling nuanced control over tone colour, vibrato, and dynamic shading.
The built-in O-ring system ensures a secure, airtight fit while protecting the instrument tenon.
The B10-4 is a specialist tool for soloists and advanced players. Its rich, full sound and long facing make it particularly effective in recital settings and when playing with piano or orchestra.
Every version of the B10-4 shares the same facing and tip opening – only the material, the tenon fitting and the tuning pitch differ. Select your version in the Bore menu above.
