Cook is holding a guitar fitted with a prototype Gizmotron, (aka The Gizmo), an effects device invented by Godley and Cream, which uses serrated wheels to produce a bowing effect on guitar strings. Cook contributed to Godley and Creme's concept album 'Consequences', which was intended to showcase the Gizmotron. The device was later marketed commercially, but proved unsuccessful.
