Bore: ML -.460" (11.68 mm)
Bell: L – 5" (127.00 mm) Yellow Brass Bell with #1 taper

The B1 was the preferred Bb trumpet of Renold Schilke and the basis in design for the other B series instruments. Distinguished by its free and open feel, this trumpet is among our most popular models, allowing the player the diversity in sound color from a rich, full bodied dark sound to a brilliant ringing tone when desired.
