Ibanez RGRTB621 Iron Label Guitar in Black Flat

The RGRTB621 is a compact, fast-playing instrument built for modern metal and extended-range work. Its lightweight construction and thin neck profile deliver hours of comfortable playing, while the neck-through design provides superior sustain and upper-fret access. Black Flat finish gives this Iron Label model a professional, understated appearance on stage.

Playability & Feel

Neck-through construction pairs a maple and walnut Nitro Wizard neck with nyatoh body wings for a balanced, responsive feel that cuts through live mix. The 24-fret ebony fingerboard with jumbo frets accommodates two octaves and fast position shifts, while the 25.5" scale and 43mm nut width create a comfortable, modern grip that reduces fatigue during marathon gigs and rehearsals.

Tone & Electronics

DiMarzio Fusion Edge humbucking pickups deliver articulate, high-output tones that sit well in a live mix and handle aggressive playing styles with reliability. The dyna-MIX10 switch provides ten distinct sound variations, allowing you to dial in everything from tight rhythm tones to expressive lead voices without changing pickups—invaluable when you need tonal range without the weight of extra instruments on a gig.
