When first bringing “the Pultec” back into production, we discussed with engineers and studio owners which model to begin with, the 2U brushed aluminum EQP-1A3 or the 3U “Pultec blue” EQP-1A. The 3U EQP-1A preceded the EQP-1A3 in original production (1961-1971 vs. 1971-1981) and definitely had more of that 1950s aesthetic. But given that they are comprised of the exact same components and have the same specs, the consensus was that the more compact EQP-1A3 made more sense in today’s space-conscious studio environment. However, after hearing for the initial 5 years of EQP-1A3 production “when are you going to do the 3U blue unit?” we finally relented and brought the EQP-1A back into production as well. So you choose which one you prefer. We think they are both pretty awesome products.
