The UV777P is a Universe series seven string solid body electric guitar model introduced by Ibanez in 1998. It is a signature model of American guitarist Steve Vai which was made in Japan by FujiGen. In the US market is was referred to as simply the UV777 although that name refers to an earlier model.
The introduction of the UV777P in 1998 was a full-fledged return for the UV series after a production halt in 1995 and the sobered UV7S model in 1997. For the UV777P Ibanez went all out with full body and neck binding, disappearing pyramid fingerboard inlay and a special "Light Without Heat" pyramid logo behind the bridge.
In terms of specifications, the UV777P went through a couple of changes: In 2003 the Lo Pro Edge 7 tremolo was replaced with the new Edge Pro 7; in 2005 it got a five-ply neck like most Japanese made models. Addition for 2010 is the return of the Lo Pro Edge 7 tremolo.
In catalogs and on websites the DiMarzio Blaze II pickups are sometimes referred to as DiMarzio Blaze (without the II) by both Ibanez and DiMarzio. These are the same pickups with the same model numbers (DP700, DP701 and DP702).
