Looking for advice. A couple of months ago, I purchased a new top-of-the-line Yamaha flugelhorn. Right out of the case I noticed a couple of small issues with the valves. The second valve was a bit sluggish compared to the first and third. I wrote it off to "perhaps a weak spring" and resolved to order some new springs. The other issue I noticed was related to the first valve. If my first finger does not push the first valve more-or-less "straight down" and pulls the button a bit to the right when depressing the valve, I can feel a slight, although short-lived hesitation of the valve to return upward. Again, I wrote if off, thinking "probably just needs to get worn in." Last night, however, when playing with a group, and playing a prolonged note using second valve; when released, the valve stuck twice (staying down by itself) for about one second each time. This is a brand new horn which has been treated like a newborn baby. Never dropped, dented scratched or handled roughly. No marks, nothing. I would appreciate any ideas people could give me regarding causes of the problems and solutions. My situation is complicated by the fact that I live in Mexico and have no instrument repair people within a few hundred miles of my home. I understand that this next request is next to impossible, but here goes. If anyone reading this knows of a good instrument repair person in Guadalajara (an 8-hour bus trip from here), I'd appreciate a lead. I'm willing to go if I must. Thanks all.
