With internal enhancements over the MKII version and a look that matches other Premier-series modules, the Golden Age Project EQ-73 Premier is the company's flagship 3-band equalizer. It uses vintage-style electronics and high-quality components from Carnhill and Burr Brown in the signal path to deliver classic tonality for musicians, producers, and audio engineers. Balanced XLR and 1/4" I/O connectors enable traditional operation with professional outboard gear, while the 1/4" TRS insert jack provides unbalanced connectivity for easy insertion into insert jack-equipped Golden Age Project gear or other unbalanced audio equipment.

Built in the style of a classic 1073 EQ module, the EQ-73 Premier's Class-A circuit has stepped frequency controls that reach from 20 Hz to 24 kHz, a dual inductor-based midrange bell-type band, and shelving filters for the low and high bands. Apply generous gain to each band—the low and mid bands have ±15 dB, while the high band has ±18 dB—and bypass individual bands via the dedicated EQ in/out switches between each band's frequency and gain controls.
