Description

Ibanez built the GRG7221MMLB as part of the GRG (Gio RG) sub-line, positioning it as an entry-level seven-string in the broader RG family. The model carried the RG Gio Series designation and was finished in Metallic Light Blue.

The guitar was constructed with a poplar body and a maple neck carrying the GRG7 profile. The maple fretboard ran 24 jumbo frets with black dot inlays, a 400mm radius, and a 648mm (25.5") scale length. Nut width measured 48mm, widening to 68mm at the 24th fret, with neck thickness of 20.5mm at the first fret and 22.5mm at the twelfth. The plastic nut fed into an Ibanez F107 bridge set at 10.5mm string spacing. Both pickup positions carried passive, ceramic-magnet Infinity R humbuckers. All hardware was finished in black. Factory tuning was set B–E–A–D–G–B–E low to high, with a string gauge of .009/.011/.016/.024/.032/.042/.054.

Owners sourcing replacement parts should note that the F107 bridge accepts strings at 10.5mm spacing, and the 48mm plastic nut is a standard dimension on this platform — a qualified guitar technician can confirm compatible replacements for either component.

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.

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.

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.
