Question. I'm having trouble with the valves with my newly purchased King 601. I'm not sure if its a problem with the way they're seated in the casings or not but as of right now, I can't get a sound out of the horn. On my Boosey & Hawkes, the valves can only seat one way. On this horn, however, they seat almost any way I place them. The pistons move up and down with ease however I either get a very distorted sound or no sound at all. Any help or advice would be appreciated. I'll keep tinkering with them in the interim.
