The Ibanez RGRT421‑WK brings a darker, more aggressive twist to the classic RG formula with its neck‑through construction and rugged Weathered Black finish. The reversed headstock and sleek, contoured body give it a commanding stage presence, while the multi‑piece maple/walnut neck provides exceptional stability and sustain. This is a guitar built for players who want the speed and precision of the RG series with the added resonance and premium feel of a neck‑through design.

Loaded with Ibanez Quantum humbuckers, the RGRT421 delivers tight, articulate low end and fast transient response—perfect for modern metal, prog, djent, and high‑gain worship tones. The bridge pickup offers punch and clarity for rhythm work, while the neck pickup provides warmth and smoothness for leads and cleans. The fixed bridge ensures rock‑solid tuning stability under heavy riffing or alternate tunings, and the 24‑fret jatoba fingerboard with jumbo frets gives you effortless access to fast runs, bends, and extended‑range phrasing.

Bold, stable, and built for performance, the RGRT421‑WK is a standout choice for players who want the power and feel of a neck‑through RG without the premium price tag. Its combination of sustain, comfort, and modern tone makes it a stage‑ready workhorse for any heavy or technical style.

At Newell’s Music in Greenwood, SC, every guitar we sell is handpicked for quality, tone, and player appeal. We don’t just stock boxes—we inspect, set up, and fine‑tune each instrument to ensure it’s stage‑ready from day one. Every guitar comes with our lifetime adjustment service, and we re‑inspect before delivery or pickup to guarantee your instrument arrives safely and performs flawlessly. That’s the Newell’s Experience.
