The A47X is the newest member to the Bach Artisan line of trombones. It features a design that was developed through extensive research to achieve a balanced resistance and improved air flow throughout the valve section. This result led to the X wrap design, creating a truly even feel in and out of the valve range that extends throughout the most expansive registers. Performers demand an instrument that can be pushed to the limits, the A47X delivers that and so much more. This model also comes with a detachable flare as the Peter Steiner signature model, A47XPS.
