Acustica Audio has introduced the next generation of its passive equalizer plugin which combines classic analog tone with dynamic harmonic control.
Building on a rare 7-band EQ design from the 1960s, version 2 of Rust is powered by Acustica’s Nova engine. The plugin goes beyond static equalization, introducing level-dependent saturation through a fully integrated preamp stage.
The original design behind RUST is often considered one of the “Holy Grails” of classic equalization. An ultra-rare, all-analog passive unit, used on countless iconic records, it helped define the sound of an entire musical era. Developed in the 1960s by Motown engineers, this ultra-rare passive 7-band EQ helped shape the sound of artists like Stevie Wonder, Marvin Gaye, Diana Ross, and The Jackson 5, contributing to the birth of the timeless Soul and R&B sound.
With fixed frequency points at 50 Hz, 130 Hz, 320 Hz, 800 Hz, 2 kHz, 5 kHz, and 12.5 kHz, its design delivers a punchy, warm, and highly musical response that became a defining element of an entire musical era. RUST 2 preserves that legacy while extending it through a new generation of dynamic processing and control.
Available for Windows and macOS in VST3, AU and AAX plugin formats, Rust 2 is on sale for the intro price of €59 EUR until June 3rd, 2026 (regular €149 EUR). Owners of the original Rust or Nova are eligible for a custom upgrade path.
