【Bruno Tilz Neustadt / Aisch 5G 3】 This is a tenor trombone mouthpiece made by Bruno Tilz, a German mouthpiece manufacturer. This is a BAKO model, one of the company's main models. Similar to Bach, it has a moderate and standard shape and weight, but compared to Bach, it feels slightly softer on the mouth, and the sound seems to contain more overtones. The size is 5G, one of the most standard sizes. There is some blackening characteristic of silver plating on the shank insertion area due to aging, but there are no problems with use, and the condition is good as it has hardly been used.
