All I can say from my few hours on her is there more of everthing. The most even scale horns I've EVER played/owned were all Yamahas. The TJ Raw XS I had was very good and even also and now my AS horn is very very even. I will put up a little review soon. All I can say now is its just a fantastic player.Nothing seems wrong,odd or out of place. As I said when I tested it at the start of the year it is the loudest horn I've ever blown. Scary when you push it.
