Korg AX3A Acoustic Guitar Modeling Processor
Brand
KORG
The Korg AX3A is a dedicated, ultra-portable multi-effects floor processor engineered explicitly to enrich and transform the live sound of acoustic-electric guitars. Standard acoustic pickups often suffer from a sterile, plastic, or overly bright tone when plugged directly into a PA system or amplifier. The AX3A solves this entirely by utilizing Korg's proprietary REMS (Resonant Structure and Electronic Circuit Modeling System) technology. This advanced digital sound engine replicates the deep body resonances, rich woody timbres, and complex air-vibration characteristics of world-class acoustic instruments, turning a basic piezo pickup signal into a lush, studio-miked performance.
The Korg AX3A is a multi-effects processor designed specifically for acoustic guitarists who want to enhance and shape their natural instrument tone with professional-quality modeling and effects. Built on Korg’s REMS (Resonant structure and Electronic circuit Modeling System) technology, it delivers realistic acoustic guitar simulations, body resonance modeling, and studio-grade effects in a compact, pedal-style unit.
Part of the ToneWorks AX3 series, the AX3A focuses on transforming piezo pickup signals into rich, natural acoustic tones while offering a wide selection of effects for live performance, recording, and practice applications. It is optimized for simplicity, portability, and fast sound shaping on stage.
Acoustic Guitar Modeling Engine
The AX3A uses Korg’s REMS modeling technology to recreate the sound characteristics of high-end acoustic guitars, including body resonance and microphone placement simulation.
