 Two more prototypes were commissioned (which makes them four in total), another string through body example (later accidentally sold at NAMM) and another black and brass tremolo model with reversed shark fin inlays.Rhoads died in a plane crash in March 1982, before these two guitars were completed, and before he could give Grover any feedback.These revised prototypes would become the first guitars sold to the public under the Jackson Guitars brand name.
