Description

Ibanez built the GRGM21MWNS as part of the miKro Series, a line designed around a reduced-scale format. The model sat at the entry level of the GRG family, offering a compact instrument on a 22.2-inch scale with a full 24-fret maple fretboard.

The guitar was constructed with a basswood body and a maple neck, with black dot inlays marking the fretboard positions. Hardware ran to chrome throughout, including the Ibanez F106 bridge set at 10.5mm string spacing. Passive ceramic Infinity R humbuckers occupied both the neck and bridge positions. The nut measured 41mm wide in plastic, the neck profile measured 19.5mm at the first fret and 21.5mm at the twelfth, and the fretboard carried a 400mm radius. The instrument left the factory strung to standard E-to-E tuning with a .010–.046 gauge set.

Owners working on setup or sourcing replacement hardware — including the F106 bridge, Infinity R pickups, or a 41mm plastic nut — should consult a qualified guitar technician familiar with short-scale instruments to ensure correct fit and intonation.

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.

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.
