Ibanez RGRTB621 Iron Label Guitar – Black Flat B-Stock

The RGRTB621 Iron Label delivers a thin, fast neck profile and supremely balanced weight that makes extended playing sessions feel effortless, even during aggressive passages across all 24 frets. This neck-through design provides the kind of upper-fret access and sustain that modern metal players expect, with a satin Black Flat finish that hides fingerprints while projecting a professional, no-nonsense aesthetic. The B-Stock unit carries only a cosmetic finish crack on the player's right arm area—zero impact on playability or performance.

Playability & Construction

Neck-through-body architecture with a 5-piece maple and walnut Wizard III neck ensures maximum resonance and seamless fret access, while the 24-fret ebony fingerboard with jumbo frets responds fast and delivers snappy high-end articulation. The 43mm nut width and carefully shaped neck profile make this guitar equally comfortable for speed runs and chord work, and Gotoh MG-T locking machine heads keep tuning rock-solid under demanding performance conditions.

Tone & Electronics

A pair of DiMarzio Fusion Edge humbucking pickups delivers tight low end and crisp highs without muddy midrange—ideal for modern metal's clarity demands. The dyna-MIX10 switching system with Alter Switch unlocks ten discrete pickup combinations, including realistic single-coil tones, while the mono-rail bridge isolates each string for enhanced sustain and cleaner note definition.
