Ibanez built the GRG131DXBKF as part of the GRG sub-line within the broader RG Gio Series, positioning it as an entry-level RG-format electric guitar. The Gio Series served as Ibanez's accessible tier of the RG platform, carrying over the core construction and hardware language of the main RG line in a more attainable package.
The guitar is built on a Poplar body paired with a Maple neck and a bound Purpleheart fretboard bearing Red Sharktooth inlays. The fretboard runs to 24 Jumbo frets at a 648mm (25.5") scale length and a 400mm radius. Nut width measures 43mm, widening to 58mm at the 24th fret, with neck thickness of 19.5mm at the first fret and 21.5mm at the twelfth. String spacing at the bridge is 10.5mm. Hardware throughout is finished in Black, including the F106 bridge. Pickups are a matched pair of passive, ceramic-magnet Infinity R humbuckers at neck and bridge positions. The guitar left the factory strung standard E-to-E with a .010–.046 set.
Owners sourcing replacement parts — frets, nut blanks, bridge saddles or pickups — should verify measurements against the figures above before ordering, as tolerances vary across components. A qualified guitar technician or luthier can assist with setup adjustments, fret work or hardware installation specific to this instrument.
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.
