Feel free to comment if you'd like to negotiate the price. B♭ Clarinet Phonic Ring (for the upper joint) I'm selling this because I don't use it much anymore. I've only used it a few times. I had it attached between the mouthpiece and the upper and lower joint connections. The following is a quote: "From JLV, which brought a new wind to the ligature world with its innovative design, a new product has been released. After years of research into how materials resonate, the "Phonic Ring" has finally been completed. It prevents vibrations from being lost at the joint and maximizes the potential of the instrument. Please try the unprecedented playing feel, expansive sound, and rich resonance!"
