The Ibanez RG421 electric guitar features a thin, flat, and fast Wizard neck that’s strong and sturdy and offers unlimited playability. It features a two-octave, 24-fret jatoba fretboard that also provides a wide tonal range. The jatoba has a reddish-brown color and produces a rich mid-range with a crisp high end. The jumbo frets contribute to smooth playability, especially for single-note playing, while the meranti body provides a scooped mid-range with a sweet tone.

The Quantum pickups provide accelerated bass response for exceptionally fast tracking of high-speed staccato riffing with crushing mid-range and precise high-end articulation. The F106 bridge enriches sustain and makes string height adjustment able to be done easily and independently.
