Enigma Filter

Enigma Filter

The Korg A3 is a digital multi-effects processor popularized in the late 1980s and early 1990s, known for its high-quality reverbs, delays, pitch shifting, and modulation effects. It features programmable presets, MIDI compatibility, and a distinctive, lush sound character. The A3 gained notoriety for its use by artists like The Edge of U2, particularly for its unique shimmer and infinite sustain effects, making it a sought-after unit for both studio and live applications.
