Benjamin Appel about his new bass trombone: “The new Bass Trombone “Orchestra symphonic” is characterised by an easy response and a warm sound in all levels. With the huge bell (diameter 270 mm) and the new “open flow”-valves you can also prompt play at Bruckner and Wagner extreme volume, whereas the tone is never been pushed. Because of its flexibility, it is a truly succeeded bass trombone convincing not only in an orchestra, but also in brass ensembles!”
