Welcome, you are looking at an exciting JEM Universe example.
This is the Vai Owned 1991 Ibanez JEM Universe 7-String Electric Guitar.
25.5" scale. 48.5mm nut width. 8 lbs 3 oz.
.70"-.80" 1st to 12th fret neck depth.
This Universe has a fantastic backstory.
This was one of Steve Vai's studio guitars, and, from Vai's recollection was used on projects, he cannot recall which ones however.
The guitar was soon after gifted to Mike Hartman, a friend of Vai's, who later joined the DLR Band and recorded 2 songs on that album- King Of The Hill and Indeedido.
There are some very cool items included- a signed Passion and Warfare ad, a personal note from Vai to Hartman, handwritten on Mothership track listing paper, and a Fire Garden postcard from Vai to Hartman.
When Steve gifted the guitar to Mike he also wrote a note on the back of the guitar.
Sadly Mike Hartman passed away in 2000.
Condition-wise there are all the marks you'd expect from a 'stunt guitarist' like Vai, and the typical glue repair between the trem and pickup routes.
This is a fantastic chance to own an instrument from Steve and Mike's personal collections- set up and ready to play.
Don't pass this by!
