Legendary knobs

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.


The programs:

Carefully sampled @ 44.1kHz and 96kHz, without introduction of noise or aliasing, in a professional recording studio with custom converters built specifically for NAT3 which outperforms $20k commercial converters. High end cables, with particular care to the connections, levels and impedance matching were used to translate the sonic qualities of this priceless devices into the Nebula software technology. Every volume change, gain change, frequency change is tested and accurately programmed without destructive digital processing for optimized sound and then compared to the original device. The result is a virtually indistinguishable digital replication of this landmark device.
The programs don't sound processed, harsh or digital as most plugins do, but instead sound like a natural extension of the original audio, gluing your tracks in the mix with an analog vibe.
