Ibanez built the GRGA120BKN as part of the RGA Gio series, positioning it as an entry-level take on the RGA body format — a line designed around heavier playing styles. The Gio designation placed it at the accessible end of the Ibanez electric guitar range.
The guitar is constructed with a poplar body and a maple neck carrying a bound purpleheart fretboard with white dot inlays. Twenty-four jumbo frets sit across a 400mm radius board, with a nut width of 43mm tapering to 58mm at the 24th fret. Neck thickness measures 19.5mm at the first fret and 21.5mm at the twelfth. The 648mm (25.5") scale feeds into a T102 tremolo bridge with 10.5mm string spacing. Two Infinity R ceramic humbuckers — one at the neck, one at the bridge — handle passive pickup duties, and all hardware is finished in black. The guitar left the factory strung with a .009–.042 set in standard E tuning.
Owners sourcing replacement parts should note that the T102 tremolo bridge and Infinity R humbuckers were Ibanez-specific components at this tier; a qualified guitar technician can advise on compatible substitutes for either unit.
STRAIGHT TALK
What Stands Out
Keep In Mind
From the people who own them
Nothing in The Vault is for sale. These records exist so the instruments stay documented after the manufacturer moves on — and the most useful part of that record is what owners add to it.
Owner photos
Put yours on the record.
The catalog shot showed one finish, under one light, a long time ago. Yours has been played. Photos from owners are what the next person finds when they are trying to identify a part, match a finish, or work out whether the one they just bought is really what the seller said it was.
What do you know about this one?
Specs only go so far. What actually fits, what breaks first, what the factory got right and what everyone ends up changing — that lives with the people who own them, not in a datasheet. Post what you know and it stays on this page for whoever comes looking next.
