Description

Ibanez produced the GRGM21MMPL as part of the miKro Series, a line of short-scale electric guitars built around a reduced scale length. The model sat at the accessible end of the GRG family, designed for players requiring a more compact instrument without departing from a conventional electric guitar layout.

The GRGM21MMPL was constructed with a basswood body and a maple neck carrying a maple fretboard with black dot inlays. Twenty-four medium frets ran the 22.2-inch scale, with a nut width of 41mm and a fretboard radius of 400mmR. The neck measured 19.5mm thick at the first fret and 21.5mm at the twelfth. Passive ceramic Infinity R humbuckers occupied both the neck and bridge positions. Hardware throughout was finished in chrome, including the Ibanez F106 bridge, which was set to a string spacing of 10.5mm. The factory string gauge ran .010/.013/.017/.026/.036/.046 at standard tuning, and the nut was plastic.

Owners sourcing replacement parts — including bridge saddles compatible with the F106, Infinity R pickup replacements, or a substitute plastic nut sized to the 41mm width — should consult a qualified guitar technician to confirm fit against the instrument's actual dimensions before installation.

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.
