The AS5 Alto is exceptionally responsive across the full range of the Saxophone with consistent tone from low to high. It produces a rich dark centered tone with remarkable projection and powerful sound filled with rich overtones that is at home in almost any playing situation ideal for classical musicians and jazz musicians that prefer a darker more traditional sound. The AS5 is constructed with Japanese brass and features ribbed construction which adds stability to the keys enabling the saxophone to maintain adjustment longer. Phoenix offers advanced professional level instruments at an intermediate level price.
