We have started handling "Silverstein ALTA AMBIPOLY REEDS", made of a new plastic material that is water-absorbent and can be adjusted by scraping with a reed trimmer. AMBIPOLYMER is used as a to replace high quality cane. AMBI means "both" in Latin. Focusing on the fact that natural cane contains a small amount of moisture and changes the feeling of blowing and sound, it is a plastic reed that has a water absorbing quality and can be sharpened and adjusted. Long-life, homogeneous Silverstein reeds with a natural cane-like sound. Please try them out.
