The Pultec EQP 1-A is the most hallowed of all studio equipment (along with a Fairchild 670). Apparently, if you have an original one of these a holy presence descends upon your board.
The Pultec EQP 1-A can both boost and attenuate the low frequency band at the same time. Wait, what? How does this make any sense (you may ask)? Because of the original circuitry the width and curve of each of these varies, and ever setting interacts with each other. To learn more about this, see: Go ahead, boost and attenuate. The Pultec EQP-1A.
Also take a look at the UAD Pultec HLF-3C and the UAD Pultec MEQ-5
You can compare the UAD to the Waves version, IK Multimedia version, Tube-Tech’s modern version.
Hints:
Attenuation + boost!
Here is an example of how the ‘trick’ works. In the chart below, the low frequency is set to 100; Low boost is set to 4, low attenuation is set to 9. Pretty cool. No wonder people have loved this for decades. But why not just use a “real” EQ and do this? Because this is great fun and sounds so smooth, and don’t be such a sourpuss.
