Designed by the now legendary Saul Walker in the late 60’s, this discrete EQ was first used as a modular OEM equalizer. As the industry rapidly embraced the sonic quality of this unit, it quickly found it’s way into many custom console designs becoming the standard channel module EQ when the company began manufacturing consoles in 1971. The combination of Walker’s incomparable 2520 op amp and his “Proportional Q” circuitry give the user an uncomplicated way to generate acoustically superior equalization.
