Stam Audio Engineering MEQP-1A • Mono Pultec Style Tube Equaliser

OVERVIEW

The Stam Audio Engineering MEQP-1A brings two legendary equalizers into a single unit: the iconic Pultec EQP-1A and the MEQ-5 midrange EQ. By faithfully reproducing the original tube-driven EQP-1A circuit while adding the MEQ-5’s mid-band boost and cut controls, the MEQP-1A delivers the silky highs, deep lows, and musical midrange shaping that engineers have trusted for decades.

After three years of development, Stam Audio recreated the EQP-1A design with painstaking accuracy using custom Sowter transformers (input, inter-stage, and output), three Carnhill inductors, and premium tubes, including a 6X4 tube rectifier for authentic vintage sag and response. The result is unmatched low-end weight, smooth harmonic richness, and the unmistakable tone that has made Pultec-style EQs indispensable in world-class studios.

Every MEQP-1A is hand-built in Chile with premium components such as Dubilier capacitors and Allen Bradley carbon resistors, then tested with a 72-hour burn-in process to ensure flawless operation. Optional upgrades include NOS tubes and stepped switches, giving engineers the ability to further refine their workflow. Combining heritage tone with modern reliability, the MEQP-1A is one of the most accurate and best-sounding Pultec recreations available today.
