Unlike modern parametric EQs, the Pultec uses a passive filter circuit followed by a tube gain stage to restore signal lost during equalization. This design imparts a silky sheen and rich harmonic coloration that many engineers find irreplaceable.
The most famous use of this EQ involves simultaneously boosting and cutting the same low frequency (e.g., 30Hz or 60Hz). Because the boost and cut curves are slightly different, this creates a unique "bump" that tightens the low-end while clearing out muddy low-mid frequencies. pultec eq 4download
Unlike modern parametric EQs, the Pultec is a . This means it doesn't use active gain stages. Instead, it uses transformers and tubes to add warmth and harmonics. Its unique features include: Unlike modern parametric EQs, the Pultec uses a
For users looking to add this analog warmth to their digital workstation, these versions are widely considered the best in the industry: Because the boost and cut curves are slightly
If you are on a budget, do not overlook this. Tokyo Dawn Records creates "Freemium" plugins that rival paid software.
