Description
Specially designed for Yamaha CSG clarinets — for maximum tonal resonance and intonation stability.
Available Colours & Lengths
The B4 is available in Black and Brown-Black — each in all available lengths: 54 mm, 55 mm, 56 mm, 57 mm and 58 mm. Colour has no effect on tone — purely a matter of personal taste.
The Gleichweit B4 is an ebonite barrel specifically developed for Yamaha CSG clarinets — precisely matched to their bore geometry and acoustic characteristics. The goal was to unlock the full tonal potential of the Yamaha CSG: stable intonation, a centred, focused sound, and reliable projection in every performance setting. The ringless ebonite design supports the instrument’s natural resonance and ensures an even, responsive feel and clear, precise articulation — whether in the orchestra pit, the rehearsal room, or the recording studio.
