Two iconic tube EQs in one piece of hardware

The SA-EQP1A is one of our most ambitious projects to date. Until now, there hasn’t been any comparable product that would truly respect the sound and legacy the iconic tube EQ has been offering since the 50’s. That is, at least not without a hefty price-tag.

At the beginning of the project, we weren’t sure if we wanted to build an exact replica of the EQP-1A or the popular MEQ-5. In the end, we opted to build a fusion of both equalisers into a single unit, thus adding the coveted mid-section of the MEQ-5 (200Hz to 7kHz) into the EQP-1A, in a manner that that carefully respects the ratios and frequency response of the timeless classic.

Our version uses the exact circuit topology, with the option to add or bypass the mid-section of the popular Pultec MEQ-5. Unlike other replicas, we didn’t settle for two transformers (input/output) and decided to respect the original three transformer configuration using an inter-stage transformer: a critical component to obtain that superb low-end, silky high-end and tonal shaping heaven, with the added bonus of making the unit even more stable, providing a consistent performance and a lower noise-floor. Every single knob thoroughly follows the ratio and frequency response of the classic unit, but we also added an output gain dial so that two units can be matched with ease for stereo operation.

 

The SA-EQP1A is built with premium components

With the aid of a premium input and an inter-stage transformer as well as a Sowter output transformer, inductors, JJ tubes and a fully discrete class A circuit with premium Vishay capacitors, we accomplished our goal: to offer the authentic sound palette and complete functionality at an affordable price.

The timeless technique of boosting and attenuating at the same time, to make use of the unit’s sweet EQ curves, can now be in your hands, and in your studio.

  1. assaad.lakkis

    I bought a pair of these bad boys. The bottom end on the Stam, was tight and punchy (no flubber) and resonated beautifully! The high end was silky and smooth, it was so pleasant to the ears. The sonics were deep and 3d, I love these units. Yes do believe the Hype, Stam stands up like a champion and most importantly I love what Joshua stands for in the market, these units were made with heart & soul, you can feel it. Best investment I made! Thank you

    Gracias Joshua van der Stam y Camila junto a todo el equipo de Stam Audio que está detrás de estos maravillosos productos.

    Es increíble la magia que tiene en las voces solo aumentando los 100 hz y los 10Khz, brillan! Y le da una presencia tremenda.

    Ni hablar de la tarola y principalmente el KICK!!.
    en TODO brilla esta unidad.
