Ibanez RGRTB621 Guitar in Black Flat B-Stock 3804 vs Ibanez RGRTB621 Guitar in Black Flat B-Stock 4421
Both are the same RGRTB621 model in identical Black Flat finish, but Product B specifies jumbo frets, 25.5" scale length, 43mm nut width, and Gotoh locking tuners—details absent from Product A's listing. Product B's more complete specification sheet makes it the safer choice if these hardware details matter to you; Product A is a comparable B-stock unit where some specs weren't documented.

Frequently asked questions
What's the difference between these two B-stock units?
Both are the RGRTB621 with identical core features: neck-through construction, DiMarzio Fusion Edge pickups, dyna-MIX 10 switching, and ebony fingerboard. Product B's listing includes explicit details on jumbo frets, 25.5" scale, 43mm nut width, and Gotoh tuners; Product A omits these specs but is otherwise the same guitar.
Who should pick the RGRTB621—a metal or djent player?
This guitar excels for modern metal, djent, progressive, and extended-range styles. The high-output DiMarzio pickups, tight rhythm tones, and articulate lead response suit aggressive playing. It's not ideal for blues, jazz, or country.
Is the 25.5" scale and jumbo frets standard on this model?
Product B confirms 25.5" scale and jumbo frets as RGRTB621 specifications. Product A doesn't list these details, but they are typical for this Iron Label model aimed at extended-range and metal players who prefer longer scales and larger fret crowns.
What skill level does this guitar suit?
Both are designed for intermediate, advanced, and professional players. The thin neck profile and fast fretboard are built for experienced performers, though an ambitious intermediate player with good technique could handle it.
