The GOLD standard for professional Bb trumpets. The Bach 180 series trumpets are the number one selling professional trumpets in the world. The 180S37 features a #37 one-piece hand-hammered professional bell that produces a warm sound with great projection allowing this instrument to work well in multiple musical settings—from jazz to concert or solo playing. The #25 leadpipe allows for slight resistance that is effective in centering tone production. The silver-plate finish provides a controlled brilliance to the overall sound. These features combined with a .459" medium-large bore allow the player to produce a well-rounded sound well suited for all types of music. Includes case and mouthpiece.
