JS 4

Ibanez JS4 Story

The Ibanez JS4 was sold between 1992 and 1993. It’s basically a JS1 with a special custom graphic Electric Rainbow designed by one of Joe’s sister, Joan Satriani. Just like the JS3 which was painted by Donnie Hunt and the JS5 by another of Joe’s sisters, Carol Satriani.

The only differences with the JS1 was the Lo Pro Edge tremolo that replaced the Edge and the graphic finish (the new JS1 from 1992 also had this feature). The body is still in American basswood featuring a 22 fret maple JS neck with 6105 frets inlaid with pearly dots.

The JS4 is now a collection guitar due to its rarity.
