Awesome versatile guitar! Thinning the herd. I purchased this from Sweetwater just last year and had it professionally set up by Sweetwater and nut was replaced with Tusq at that time. All of the Sweetwater paperwork and original nut will come with the guitar as well as a like new SKB Les Paul style hard case.
From Sweetwater where I bought it:

The Ibanez AR520 is built for players who love the look of an Ibanez solidbody but want to add a dash of hollowbody character to their signal. This guitar has a chambered maple/okoume body with a carved maple top. Two Super 58 Custom humbuckers with Tri-sound electronics give the Ibanez AR520 undeniable tonal tenacity; the hollowbody construction adds an airy quality, yielding a sound that guitarists here at Sweetwater simply can't get enough of. The Ibanez AR520 also features a Gibraltar Performer bridge and Quik Change Ultra tailpiece, providing long sustain and tuning stability. Plus, the 3-piece maple neck and nearly non-existent neck heel offer supreme playing comfort.
