All superstrat guitars have a overal shape that derives directly from the Fender Stratocaster. As opposed to more classic guitar-shaped models like the Gibson Les Paul, the Stratocaster has offset double cutaways and a six-in-line headstock. Over the time the shape was modified by most guitar manufacturers. This has resulted in generally sharper, more aggressive body styling than the original Fender design, especially in the Ibanez RG series.
