Hello. I play tenor. I play four or five times a week. I have two tenors. My first one was identified by a leaky pad in the crane. I used my spare crane for now but now another leak has occured in the body. The sax is suddenly very hard to blow and it octaves on middle a, b or c. I figured it would be a pad that's normally closed and i noticed the g sharp pad isn't sitting exactly true. I pressed it down with my finger when playing problematic notes but it didn't solve them. Any ideas?
