Vintage Tube Program EQ

This module is based on what is universally known as one of the best and most musical program EQs ever made, the Pultec® 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 DSMâ„¢ and new SCCâ„¢ 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.
