The JoyKey is the proven solution for effortlessly and effectively removing water automatically from brass instruments. The heart of the JoyKey is the high-tech WaterWick replaceable metal filter. Moisture in brass instruments gravitates to the lowest point possible. Here, the JoyKey allows the water to continuously drain out of the instrument. This ensures that the inner taper remains constant by completely eliminating water build up in the targeted tubing section. Most importantly, the WaterWick maintains the integrity of the air column of the instrument. Each pack lastst about 4 months. Replacement packs are available.
Installation by a qualified repair technician is required.
