Description

Ibanez built the GRGM21MBLT 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, positioning it as an accessible electric guitar with a compact footprint suitable for players requiring a shorter reach.

The guitar was constructed with a basswood body and a maple neck carrying a maple fretboard dressed with black dot inlays. Twenty-four medium frets run across a 400 mm radius board, with a 22.2-inch scale length and a 41 mm plastic nut. The neck profile registers 19.5 mm thick at the first fret and 21.5 mm at the twelfth, tapering from 41 mm at the nut to 56 mm at the twenty-fourth fret. Two passive ceramic Infinity R humbucker pickups — one at the neck, one at the bridge — feed the signal chain, mounted on a body fitted with the Ibanez F106 bridge at 10.5 mm string spacing. All hardware is finished in chrome. The guitar left the factory strung in standard E-to-E tuning with a .010–.046 gauge set.

Owners sourcing replacement parts — including bridge saddles compatible with the F106, Infinity R pickup substitutes, or a direct-fit plastic nut at 41 mm — should consult a qualified guitar technician or luthier who can verify measurements against the physical instrument before ordering.

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.
