Description

Ibanez built the RG7421PBSBF as part of the RG Series, positioning it as a seven-string instrument with a visually distinctive Poplar Burl top over a Meranti body. The Sapphire Blue Flat finish was the defining cosmetic feature of this variant within the line.

The guitar was constructed around a three-piece Maple Wizard II-7 neck — a profile associated with Ibanez's emphasis on speed and low action — joined to a Jatoba fretboard carrying white dot inlays across 24 jumbo frets. The 648mm (25.5") scale length and 10.5mm string spacing at the F107 bridge were standard reference points for the platform. Nut width measured 48mm, widening to 68mm at the 24th fret, with a neck thickness of 19mm at the first fret and 21mm at the twelfth. The fretboard radius was 400mmR. Both pickup positions carried passive, ceramic Quantum-7 humbuckers. Hardware throughout was finished in black. The guitar left the factory strung with D'Addario EXL110-7s (.010/.013/.017/.026/.036/.046/.059) in standard seven-string tuning (low B to high E).

Owners sourcing replacement parts — including bridge saddles sized to the 10.5mm string spacing, Quantum-7-format pickups, or a correctly dimensioned nut blank — should consult a qualified guitar technician who can confirm fit against the instrument in hand.

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.
