This module is based on what is universally known as one of the best and most musical program EQs ever made, the Pultecu00c2u00ae EQP-1A. Extremely accurate modeling of two real world units, known to have the sound, with sonic performance that is indistinguishable from the originals, thanks to IK`s DSMu00e2u201eu00a2 and new SCCu00e2u201eu00a2 resulted in this great sounding plug-in.
Released in 1951 the original Pultec EQP-1 was the first program EQ in music history based on passive filter circuits. In this first version though the unit had a weak point caused by its passive filtering circuitry, which was the inherent gain loss. It was then compensated in the following EQP-1A by adding an output makeup gain stage based on 12AU7, 12AX7 and 6X4 tubes, which also contributed to its euphonic and musically rich sound.
The modeled version has that same character and musicality, which is immediately noticeable when performing broad frequency boosts. Closely replicating the frequency centers, boost/cut ranges and filters bandwidth makes it easy to use it for classic EQing techniques it’s know for, like the “Pultec EQ Trick”.
