The Francois Louis Pure Brass Ligature for Bb clarinet is precision-crafted in Belgium to enhance natural reed vibration and tonal resonance. Made from solid brass with a polished silver finish, it features a single top screw for simple, reliable tightening and a solid brass pressure plate for consistent contact and centered response. Integrated brass resonators support free vibration, producing a richer, fuller tone with balanced resistance and improved projection. These ligatures are compatible with most standard rubber Bb clarinet mouthpieces, including Selmer Paris, Vandoren, Meyer, and Otto Link.
