Pulse Techniques EQM-1S3

The Pulse Techniques EQM-1S3 is a mastering variant of the legendary Pultec EQP-1A with precise stepped controls and additional frequencies.


The Pulse Techniques EQM-1S3 boasts only original-spec components and are true recreation of the classic Pultec units of the past. The EQM-1S3 is based on the EQP-1S3 which has different curves and frequency points with the low-band offering a choice of 30Hz, 40Hz, 70Hz and 100Hz and the high-shelf 1kHz, 2kHz, 3kHz, 4kHz, 5kHz, 6kHz, 8kHz, 10kHz and 12kHz (also known as KCS). Both low and high shelves offer +10dB of boost and attenuation in 0.5dB steps.


More than a clone, the Pulse Techniques EQM-1S3 is an actual recreation of the original units and are a testament of Dr Steven Jackson’s true passion and dedication to bring back one of the most sought after EQ.
