AB-SGWB Steve Gadd brushes. The AB-SGWB Steve Gadd brushes are metal brushes made in collaboration with Steve Gadd. They are mainly used on drums, but can be used on different types of percussion to obtain a particular sound. The slight curvature of the bristles prevents them from getting caught along the edges of the leathers, while the ring at the end of the handle can be used
as a knob on plates.
