Ibanez RGRT421 – Unmatched Stability and Sustaining Power

The Ibanez RGRT421 is a high-performance machine built for the dedicated metal and rock guitarist. Standing out from other RG models with its Neck-through construction and Reverse Headstock, this guitar is designed to provide massive sustain and a distinct, aggressive look that commands attention on stage.

Rock-Solid Neck-Through Design

The heart of the RGRT421 is its 5-piece Maple/Walnut Wizard III neck, which runs through the entire length of the body. This "Neck-through" construction provides massive sustain and superior vibration transfer, while the Meranti wing body adds a warm, resonant punch. The Reverse Headstock isn't just for style—it increases string tension on the lower strings, providing a tighter feel for heavy rhythm playing and drop tunings.

Precision Fretwork and Tone

The Jatoba fretboard features a reddish-brown color and produces a rich mid-range with a crisp high-end. With 24 Jumbo frets, you have a full two-octave range to explore with maximum ease and precision. For electronics, it utilizes the Quantum humbucking pickups, which are specifically designed to capture fast, high-gain passages with precise note definition and a crushing low-end response.

Reliable Hardtail Hardware

The F106 bridge offers a simple, effective design that enriches sustain and makes string height and intonation adjustments quick and easy. Like other high-end Ibanez models, it features the Mono-unit output jack, crafted from durable material to prevent loosening and contact failure, ensuring your signal stays strong through every performance.
