◻️ Denis Wick 4L ◻️ Cornet Mouthpiece ◻️ Produced a warm sound with low to high notes without difficulty (up to around hiF, which was easy for me to play). ◻️ The "L" in 4L stands for Large fitting, and it's a type that fits well with Japanese and American-made cornets like Yamaha and Bach. ◻️ Shank end is 8.95mm, shank base is 10.15mm, and length is 27.0mm. ◻️ This is a model number that is no longer manufactured. ◻️ The rim is flat and slightly thick. I'm selling this because I had another one. #Heritage #Besson #Trumpet #Flugelhorn #Piccolo #YAMAHA #Yamaha #Bach #Eric #Bob Reeves
