Description

Ibanez built the RG421AHMBMT as part of the RG Series, positioning it as a solidbody electric guitar centred on the long-running RG platform. The model carried a Blue Moon Burst finish over an ash body, with a Wizard III maple neck and a maple fretboard dressed with black dot inlays.

The guitar featured 24 jumbo frets on a 400mm radius board, with a nut width of 43mm tapering to 58mm at the 24th fret. Neck thickness measured 19mm at the first fret and 21mm at the twelfth. The 648mm (25.5") scale fed into an F106 bridge set at 10.5mm string spacing. Both pickup positions carried passive, ceramic-magnet Quantum humbuckers. All hardware was finished in cosmo black. The guitar left the factory strung with D'Addario EXL110s (.010–.046) in standard E tuning.

Owners sourcing replacement parts — including bridge saddles compatible with the F106, or pickups sized for standard humbucker routes — should verify measurements against the hardware currently installed. For setup, fretwork or any structural concerns, consult a qualified guitar technician.

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.
