- GOLD-BRASS BELL - Xeno trombones feature a heavier gauge brass and a thick-walled, one-piece brazed bell which has been hand-hammered thousands of times for the ultimate in a big orchestral sound. The F-atachment section gives a free-blowing response and the entire instrument has an evenness and balance you have to experience to believe. The tone is flexible with myriad tonal colors, and gives you both powerful projection at fortissimo and subtle control in the most delicate passages. Features Compact wrap F attachment The compact wrap helps to produce a rich, brilliant tone. |
