Pultec EQM-1A3 Tube Program Equalizer

The Pultec EQM-1A3 is the mastering version of the legendary EQP-1A3 equalizer, hand-built in the USA by Pulse Techniques. Designed with the same passive inductor-based EQ circuit and tube-driven Class A amplifier stage as the original, the EQM-1A3 delivers the classic Pultec warmth, depth, and musicality—refined for mastering and mix-bus applications with stepped controls for precision and recall.
