alexeyt,
The RG series was first introduced in 1987 as a derivative to the Ibanez JEM and Universe series by Steve Vai, contrary to the more popular opinion that Rocky George, former lead guitarist for the California based hardcore punk/thrash metal outfit Suicidal Tendencies and current lead guitarist for Fishbone was its designer[citation needed] (Rocky however was one of the first famous users of the RG model). This was believed because Rocky's initials are the same as the model. The RG in the Ibanez RG name does not mean Rocky George, in reality they mean Roadstar Guitar, although these instruments differ significantly from the original Roadstar II series, introduced in the early 1980s. One of the first guitars in the RG series was the RG550 with an Edge tremolo. It became one of the most popular guitars ever made by Ibanez and made the RG name known internationally...
