..... by Schiller manufactured in Germany, which has 1st and 3rd valve extensions that are intended to "center" or help keep the tone of the horn balanced. Seems to make sense as my memory of playing flugelhorns is that they were hard to keep in pitch, even with working valve levers... I'm wanting that sound again in my life, and I've only owned one before - an Salvation Army brand (stamped on the bell) manufactured in England. It was a bear to play, and probably of low quality.... recently, when a friend got Chuck Mangione's signature for me on a program, my serious interest was reignited!... if anyone has experience with Schiller or a quality flugelhorn (at a reasonable cost) please advice at your leisure... any input is appreciated...always in search of the good sounds.... with your generous help here at TrumpetMaster, I know I'm in good company....I've done a lot of reading on different makes, and know how each is unique, and the "must play" laws of purchasing, but your knowledge helps immensely..... thanx!
