Trombone Mouthpiece JK EXCLUSIVE 7CL SB (Large Shank, SP) [Condition] This item was purchased used. It shows little signs of use and is in relatively good condition. Disinfected and cleaned. Please check the images. [Packaging and Accessories] Box and bag are not included. Will be wrapped in bubble wrap for shipping. [Comments] JK (Josef Klier) is a German mouthpiece manufacturer. While not very common in Japan, it is a major manufacturer in Europe. JK's 7CL is about the same size as B Company's 5GS. It's a bit lighter in weight and easier to handle, and I think it works well with German-made trombones like B&S and Jürgen Voigt. Please refrain from purchasing if you are sensitive to used items.
