Key Features
Superior Playability and Stability
The GRX20 features a lightweight Poplar body contoured for comfort during long practice sessions.1 It is paired with a GRX Maple neck, known for its stability and bright tonal character.2 The fretboard is crafted from Jatoba, which offers a reddish-brown aesthetic and produces a rich mid-range with a crisp high end, making every note pop with clarity.
Powerful Infinity R Pickups
At the heart of the GRX20’s sound are the dual Infinity R Humbucker pickups (Passive/Ceramic) located at the neck and bridge.3 These pickups deliver an accurate and tight sound with excellent dynamics. Whether you are playing rhythm or lead, they maintain tonal clarity even under heavy gain settings, making this guitar an excellent choice for rock and metal.
Reliable Hardware Innovation
Ibanez has equipped the GRX20 with hardware designed to keep you playing longer.

T106 Tremolo Bridge: Featuring 6 independent saddles, this bridge allows for precise height and intonation adjustment for each string, ensuring your guitar stays in tune and plays correctly up and down the neck.4

Mono-Unit Output Jack: Unlike standard jacks that loosen over time, the GRX20 features a solid, mono-unit output jack made of durable material.5 This single-piece design prevents unwanted movement and contact failure, ensuring reliable connectivity for years to come.
