The Jupiter JTB1100 Performance series trombone is a great choice for the advancing player searching for a larger bore instrument. The 1100 features a .525" medium bore design for excellent response and air flow. The medium bore design allows the player to move into a trombone without the air support challenges of moving immediately to a large bore instrument from their student model trombone. A nickel silver outer handslide adds additional protection to the slide while helping with overall instrument response. A favorite among music educators, the Jupiter 1100 includes a case and mouthpiece and is available in lacquer or silver-plate finish.
