Modular valve section component for Bach Artisan series trombones. The Artisan rotary valve and open-wrap F attachment offers a balance between the wide-open feel of the various free-flow valves and the often too-tight feel of a traditional rotors. The system offers the player more feedback and tends to help the horn slot, making for more security in passages that require the valve, and less interference in places where the valve is not required. Replaces the former 03 valve section. -cdp
