Ibanez j.custom RG8570 — The Top of the Ibanez Line
The j.custom designation sits above Prestige in the Ibanez hierarchy, and it means something specific: these instruments are built in Japan by a small group of the company's most experienced luthiers, using the highest grades of wood available and the most refined versions of every process Ibanez has developed over four decades of guitar making. The RG8570 is the flagship six-string of that line — an instrument that competes directly with boutique builders at multiples of its price, and one of the few production guitars where the fit and finish genuinely warrant the description.
AAA Flamed Maple Over African Mahogany
The body pairs a 4mm AAA-grade flamed maple top with an African mahogany back. Mahogany supplies warmth, midrange density, and long sustain; the maple cap adds attack, clarity, and definition at the top of the frequency range. It's a classic combination, but the execution here is what distinguishes it — AAA is a genuine top-tier grade, and the Black Rutile finish is a translucent treatment that lets the flame figure read through the dark color rather than burying it. The figure varies from instrument to instrument, so each guitar in this run looks slightly different from the next.
Super Wizard Neck and Macassar Ebony Fretboard
The RG j.custom Super Wizard neck is a five-piece maple and wenge lamination. The multi-piece construction resists twisting and seasonal movement far better than a one-piece neck, and the wenge stripes add stiffness that translates into clearer note attack. The profile is thin, flat, and fast — the shape that made the Wizard name — with the "Velvetouch" satin treatment on the back that produces a broken-in feel from the first session rather than the tacky drag of a fresh gloss neck.
The bound Macassar ebony fretboard is dense and oily, producing tight lows and mids with a strong attack in the high register. It carries the Tree of Life inlay running the full length of the board — among the most intricate inlay work found on any production instrument. The 24 jumbo frets receive Ibanez's j.custom fret edge treatment, which rounds and polishes each fret end to a degree you simply do not find
