The Ibanez JEM77, also known as the JEM77 GMC (Green Multi Color), is a JEM series electric guitar model and signature model of American guitarist Steve Vai. Features include DiMarzio pickups, a Lo-Pro Edge tremolo, fluorescent green vine fingerboard inlays and a special black-and-green multicolor finish. Only 366 were produced, making them exceedingly collectible.
The guitar bodies were swirled by Darren Johansen of About Time Design creating the unique finish. Other Steve Vai models with this kind of finish are the UV77, JEM77 PMC and JEM2K.
