This model is inspired by the sound of M.C. Gregory, popular in the American jazz scene of the 1950s and 60s. Improvements to the chamber and tip opening allow modern musicians to recreate the sound made famous by the great saxophone players of the past. It has a thick body, a slight resistance, and a soft tone. Recommended for those who want to experience the sound of that era. [From the Nonaka Boeki website] I bought it used about 10 years ago and haven't used it much, but there are small scratches. The size is 5. #AltoSax #Mouthpiece #Meyer
