The Ibanez UV777, also known as the UV777 GR, is a Universe series electric guitar model and a seven-string signature model of American guitarist Steve Vai. It was introduced in 1991, one year after the introduction of the UV series.
The UV777 features a green finish, different in color to the famous "Loch Ness Green" of Vai's first Ibanez signature model, the JEM777. It sports a maple fretboard with tri-color, disappearing-pyramid inlays, and dual-color pickups. This model is quite rare, with only 340 having been made. They rarely come up at auction, and, because of their age, are rarely available in good condition.
In 1998, a new Universe was introduced also known as the UV777 in the USA. In the rest of the world including Japan it is known as the UV777P.
