The Jupiter JTB1150F series trombone is a great choice for the advancing player searching for a professional large-bore trigger trombone. The 1150F features a .547" large-bore design and a standard traditional wrap F-attachment with mechanical linkage valve for excellent response and air flow. The nickel silver outer handslide adds additional protection while helping with overall instrument response. A favorite among music educators, the Jupiter 1150F includes a case and mouthpiece and is available in lacquer or silver-plate finish.
