Check the listing for details. Golden Age Project EQ-73 MKII Vintage-style Equalizer. Condition: New. Listed at 379.00 USD. Value-packed “73” EQ For their EQ-73 MKII 3-band equalizer, the Golden Age Project based their Class A circuit on the EQ section of an exalted icon of British engineering — the legendary console module that enhanced countless hit records since its release in 1970. In a tidy, budget-friendly half-rack chassis, you get the same punchy, authoritative 3-band semi-parametric EQ, with additional frequency centers for even more flexibility. The EQ-73 MKII retains the intuitive industry-standard functionality of the vintage original, albeit without the highpass filter. For many engineers and producers, the vintage “73” is the holy grail of EQ, imparting a natural, highly musical character to any audio material, even when cranked to extremes.
