Has anyone heard of a way of lining up the valves to the actual tubing of the horn by putting some sort of hard rubber underneath the valve caps. I'm not exactly sure how it works, but by using dental tools (like the mirror used to look at teeth) you can see how off the valves are to the tubing. I've played horns with this done to them and they play much more open....does anyone know if I could go to any repair shop and get this done or if its a pretty secluded practice? Thanks
