Antoine Courtois Creation 421 "New York" Series Bb Trombone

For the first time in Antoine Courtois' history, both of these models are equipped with a specially designed bell with a cut screw ring flare, which enables these instruments to be transported in a deluxe flat case, hardly larger than a viola case, making them much more travel friendly. The screw ring on the bell flare also brings a more compact, focused sound with a lot of projection, which both players are particularly pleased with. •  Key: Bb/F •  Bore: .547''/13.89mm cylindrical bore. •  Bell: 8.46''/215mm hand-hammered one-piece yellow or gold brass bell, optional cut and fitted with a screw ring on the bell flare. •  Slide: Brass outer slide with extrusions on the top.
