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-attachment 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 colours, and gives you both powerful projections at fortissimo and subtle control in the most delicate passages.
