I have a Yamaha Custom long bell piccolo that plays pretty well. However, I played it against a new one that a friend of mine owns and wondered if I could improve on mine rather than buy a new one. (which is not an option right now. LOL) Mine is 13 years old and has some intonation issues that the new ones do not. Will a valve alignment improve things? It blows fine and I sound fine on it, so I don't know if I want to mess with the lead pipe. What I am tired of is fighting the pitch on the darn thing. The new ones seem to have improved in that area. Also, I tried years ago to have a trigger put on the first valve (like the Butler/Geyer Schilke model) but it required replacing the entire valve cluster.....which wasn't worth it. Are there options available now that perhaps were not five or so years ago? Thanks.
