ICON Trombone Mouthpiece for Large Bore Price: ¥11,000 I purchased this new for a trial, but I am selling it because the size doesn't fit. A product has been created that carries on the legacy of the mouthpiece developed by Jean-Baptiste Arban, known for the "Arban's Complete Conservatory Method for Trumpet." You can experience a wonderful playing feel, including an elegant tone, accurate attacks, and excellent response and projection. Compared to Bach mouthpieces of similar sizes, this one feels slightly smaller (around the middle of Bach 5G to 6 1/2G).
