The Gleichweit B7-4 Bb clarinet mouthpiece is one of our most popular Bb clarinet mouthpieces – designed for clarinetists who demand top-tier quality with both French-style cane reeds and synthetic reeds. A balanced combination of free response, precise control, and rich tonal depth.

The most popular model in the Gleichweit line, the B7-4 is precision-crafted on advanced CNC machinery from high-grade synthetic material. Designed for players who prefer a closed tip opening similar to the Vandoren BD5, this mouthpiece offers an ideal balance of control, projection, and tonal richness.

The built-in O-ring system ensures a secure, airtight fit while protecting the instrument tenon.

The B7-4 delivers a centered, resonant tone with quick articulation, stable resistance, and excellent flexibility across all registers. It performs equally well in orchestral, chamber, and solo settings, with reliable response in the altissimo and a wide dynamic range.
