In 2014, due to customer demand, Pulse Techniques brought back into production the 3U EQP-1A program EQ. Many of their clients prefer the look and layout of the larger unit to that of the 2U EQP-1A3 and the EQP-1A has become one of their most popular units. Almost immediately after announcing the return of the EQP-1A, they started receiving requests for the Pultec EQP-1S 3U Program Equalizer, the 3U version of the Pultec EQP-1S3. For those not familiar with the (formerly) extremely-rare EQP-1S/EQP-1S3, these products have the same wide-bandwidth line amp as the EQP-1A/EQP-1A3 units, but have modified low-frequency boost/atten response curves, add 2 additional peak boost frequencies, and most-importantly add 2 high-frequency shelf boost curves to the sonic palette.
