Its a bass Trombone (Bigger bell than regular) with a Double Trigger.
I just picked it up last week and someone told me that the slide positions could slightly vary because its a bass.
Also, if someone can find me a picture and a proper name for it online, I would greatly appreciate it I played bass trombone for 3 years and found that it is extremely similar to a tenor trombone slide. Play with a tuner to find out for yourself. If you are a beginner or intermediate player you may not even notice any difference. |
