The Pultec EQP-500X is the official 500 Series version of the legendary EQP-1A program equalizer, made by Pulse Techniques the original Pultec company. Rather than replicating the tube-based original, it follows the lineage of the solid-state EQP-1A3-SS: the same passive EQ front end and input transformer, but driven by a genuine API 2520 op-amp into a Triad output transformer. The result is the classic Pultec character broad, musical curves, that famous trick of simultaneously boosting and cutting the low end for added weight and definition with the punchier low end and tighter transients that solid-state enthusiasts prefer. The high band draws from both the EQP-1A3-SS and EQP-1S3-SS, offering an expanded set of peak boost frequencies from 1 kHz all the way up to 16 kHz. For engineers who want genuine Pultec DNA in their lunchbox, this is the real thing.
