2010 Ibanez RG8420ZD J Custom AAA Maple Top & Red Spinel Finish w/ Case & COA


+ shipping

Up for sale, a 2010 Ibanez RG8420ZD in excellent, 100% original condition and in perfect working order, complete with the original molded hardshell case, factory paperwork, COA, and case candy. Produced at the venerable Fujigen factory as part of Ibanez’s upper-tiered J Custom line, this shred-ready RG features premium fit and finish work. Features include a pair of Seymour Duncan humbuckers, an Edge Zero tremolo with ZPS3 stabilizer, and a AAA flamed maple top highlighted by the rich Red Spinel finish.

Tonewoods include an African mahogany body capped by the AAA flamed maple top and a five-piece maple/walnut neck with a 24 fret rosewood fretboard. The bridge pickup is a Seymour Duncan Custom 5, designed to recreate the tonal profile of a PAF-style pickup but deliver far more output. It’s chewy and fat, with scooped mids for optimal clarity when driven; offering searing, white-hot leads perfect for soloing and melodic work. The neck pickup is an SD Jazz (SH-2), a time-tested classic that provides pristine, bell-like clarity and fullness. This Ibanez weighs 8lbs 9oz, professionally setup here at Mike & Mike’s Guitar Bar with 9-42 strings, slinky action, and spot-on intonation.

The five-piece maple/walnut neck sports Ibanez’s RG J Custom profile shape; a slender, fast-feeling D-shaped carve with generous shoulder and rolled fretboard edges, measuring .715” deep at the 1st fret and .780 at the 12th. The rosewood fretboard is framed by flamed maple binding and features an abalone/mother of pearl tree of life inlay and 17" radius. The stock jumbo fretwire has Ibanez’s proprietary J Custom fret-edge treatment, and the frets are in fantastic shape with well-rounded crowns, showing just a hint of wear beneath the plain strings on frets 2-3. This guitar plays cleanly up the 25 1/2” scale with a straight neck reinforced by KTS titanium rods. The Top-Lok locking nut measures 43mm (1 11/16”) in width. The matching headstock sports a flame maple veneer, which has a pair of microscopic chips at the very top edge of the headstock. The stock Gotoh tuners turn smoothly and hold accurate pitch, with an even dusting of patina across the Cosmo Black plating.

All of the electronics function as intended, with the pair of Seymour Duncan humbuckers wired to the stock harness and governed by the five-way pickup selector switch with Master Volume and Tone knobs. Pickup switching operates as follows:

1. Bridge
2. Inner coils of each humbucker (coil-tapped)
3. Bridge + Neck
4. Neck humbucker coils in parallel
5. Neck humbucker coils in series

The Cosmo Black hardware has uniform surface patina, revealing the bare metal of the dome-top knurled knobs and on the Edge Zero tremolo. The tremolo actuates smoothly and bounces back to pitch reliably, remaining stable through the deepest divebombs, assisted by the ZPS3 stabilizer.

The gloss Red Spinel finish highlights the dimensional figuring on the bookmatched AAA flame maple top, with cosmetic wear limited to an area of buckle rash on the back central to the waist and a handful of faint finish scratches in the clear coat on the body as a whole. The smooth satin finish on the neck profile has been buffed to a semi-gloss through play and feels lightning fast in the palm. There is a microscopic chip on the treble-side shoulder behind fret 12 that has no impact on playability.

The original molded hardshell case is included, along with the factory paperwork, COA, and case candy.
