573EQ

Classic Inductor Equalizer

573EQ is a classic inductor-based equalizer inspired by the legendary 1073, reimagined for the modern 500-series environment. Featuring Swiss-made ELMA stepped switches across all four bands, it delivers precise, repeatable control with unmistakable analog warmth. Its carefully voiced low end, musical midrange, and open, airy highs provide both corrective precision and characterful enhancement. Balanced with modern, transparent circuitry, 573EQ integrates seamlessly into contemporary signal chains while preserving vintage tone. Whether used for shaping individual sources or adding subtle mojo across a mix bus, it delivers depth, clarity, and timeless musicality.

Classic Inductor EQ with Modern Precision
573EQ draws inspiration from the iconic 1073 equalizer, translating its musical curves and harmonic richness into a compact 500-series format. Inductor-based filtering delivers weight, texture, and a natural sense of depth that digital EQs struggle to replicate.

Fully Stepped, Recall-Friendly Control
All four bands are controlled via Swiss-made ELMA switches, ensuring precision and perfect recall. This makes 573EQ equally suitable for tracking, mixing, and hybrid workflows where repeatability matters.

Powerful Low End and Tight Filtering
The low-frequency section is fat, fast, and controlled, working in tandem with a high-pass filter to maintain clarity and focus without sacrificing impact.

Musical Mids and Airy Highs
The mid band excels at both corrective and creative shaping, while the high band delivers smooth, open top end across a thoughtfully chosen frequency range—adding definition without harshness.

Analog Mojo, Even Flat
Used as a stereo pair on a mix bus, 573EQ adds subtle analog character even with no EQ applied, enriching mixes with depth and cohesion.
