The Gravity Storm™ Neck & Bridge Model pickups were designed for Steve Vai, and are the next step in his pickup evolution. The pickups are named after a song on his album, Steve Vai: The Story of Light.Steve used to describe pickup sounds in terms of specific frequency responses. Now he describes them as flavor and texture. The flavor of The Gravity Storm™ Neck model is sweet and warm, but the texture has an edge to it. It has the depth of a humbucker with some of the bite of a single-coil.
