ESM Jazz Heaven 7 for alto saxophone. The opening is said to be equivalent to Meyer's 8MM, but it feels more like a 7, making it an easy-to-play opening. This versatile mouthpiece allows you to produce a sharp, powerful sound like a high-baffle metal mouthpiece, while still being easy to control and allowing for a relatively classical performance style. The tip and table are in excellent condition, and the design precision is very high. The logo is slightly faded, but it is still in usable condition.
