The SA-EQP1A is one of our most ambitious projects to date. Until now, there wasn’t any product that would truly respect the sound and legacy the iconic tube EQ has been offering since the 50’s. At least not without a hefty price-tag.
At the beginning, we were not sure if we wanted to build an exact replica of the EQP1/A or the popular MEQ-5. In the end, we opted to fusion both into a single unit, thus adding the coveted mid-section of the MEQ5 (200hz to 7khz) into the EQPQ/A. 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 piece to get that superb low-end, silky high-end and tonal shaping heaven, with the 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 timeless classic but we also added an output gain dial so that two units can be matched at ease for stereo operation.
With the aid of a premium Cinemag input and a inter-stage transformer as well as a Sowter output transformer, Cinemag 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 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.
