OK, Experts! It has been 2½ years since anyone made a post on this horn. What is the verdict on this horn? I’m giving this model strong consideration for ergonomic reasons. After 65 years on trombone, I can no longer hold a trombone without causing nanny-goat like vibrato on sustained tones. I bought a Schiller Elite to determine if I could hold a euphonium without my essential tremors interfering. I need Your input on this model if you have any. Thanks for your help!
