I have a old Couesnon Flugel that is in excellent condition and free of any major dings or dents and plays and sounds very good. After playing a short time, spit collects in the horn and I have to remove the valves to empty it out. I imagine if I want to really use this horn, it will have to be modified.

Now for a few questions...

1) What modifications should be done to this horn to make it's use practical?

2) I want a very nice professional flugelhorn. Will the modifications to this horn bring this horn up to a professional level horn? My price range will be up to $2000.

3) The valves on this horn seem old and tired and don't move smoothly like my new horn I just purchased (yamaha xeno silver) -- can these be upgraded or improved?

Thanks in advance -- David
