With new level knobs and internal enhancements over the MKII version, the Golden Age Project EQ-81 MKIII is a 4-band equalizer that uses vintage-style electronics and Tantalum capacitors in the signal path to deliver classic tonality for musicians, producers, and audio engineers. Its balanced XLR and 1/4" I/O connectors enable standalone use, while its 1/4" TRS insert jack provides unbalanced, integrated circuit-free connectivity for easy insertion into insert jack-equipped Golden Age Project gear or other unbalanced audio equipment.

Built in the style of a classic 1081 EQ module, the EQ-81 MKIII's Class-AB circuit has stepped frequency controls that reach from 33 Hz to 15 kHz, inductor-based mid bands with hi-Q switches, and bass and treble bands with selectable shelving/bell modes. Apply up to 18 dB of boost or cut per band, and bypass individual bands via the Off position on each band's frequency selector.
