The Ibanez UV777-GR is part of the Ibanez Universe Series, which was launched in 1991 and made a mass-produced 7-string electric guitar available to the general public for the first time. In addition, the UV777-GR differs from other models in the Universe series with its eye-catching green finish. Production of the UV777-GR was limited to just two years, from 1991 to 1993, and a total of only 340 units were produced during that time. This limited edition contributes to the exclusivity and high demand for this model.
