Professional musicians worldwide recognize the Bach name for outstanding quality. The same American craftsmen that build the professional Bach Stradivarius instruments also create the intermediate and beginner Bach models. Using many of the same materials and methods as the Stradivarius line, Bach trombones represent an outstanding value. Band directors highly recommend Bach instruments for students because of their durability. Hand-hammered yellow brass bells produce the clear and resonant tone quality that Bach brass instruments have become famous for. Brass outer slides are drawn to a hard spring temper for durability. Seamless inner slides, created from a solid nickel silver alloy, are chromium plated for smooth action and resistance to body acid. Meticulous fitting and alignment of the slides give Bach trombones a sensitive response that can't be duplicated.
