The Bach 183S Stradivarius flugelhorn is famous for it’s signature Bach sound. The .401″ bore promotes an ease of response while the one-piece hand-hammered professional bell produces a warm sound with full projection. The silver-plate finish provides a controlled brilliance to the overall sound. The 3rd valve trigger allows for quick and accurate adjustments. The 183S flugelhorn is a well rounded instrument at home in multiple musical settings.
