If we're talking about elusive vintage Pultecs, the EQP-1S3 takes the cake. After reissuing a 2U version, the company has shrunk their classic equalizer further with the 500 Series EQP-500S. Spec'd just like the classic, the EQP-500S delivers the signature Pultec punch and warmth that made the original a coveted piece of outboard in the 1970s, along with the modified high band that includes shelving at 5kHz and 10kHz, plus alternate low-frequency selections. Based on the esteemed API 2520 op-amp, the EQP-500S serves up that inimitable Pultec sound, with the control you need to EQ your tracks to perfection.

• Boost, cut, or both - it all sounds great
• Vintage solid-state classics
• Nourish your tracks with the stuff of legend
• Boost, cut, or both - it all sounds great

Take a look at the Pultec EQP-500S and you'll see it's not designed like your typical equalizer. The 2-band design basically gives you flexible low shelving, along with broad-bandwidth midrange peak control. Because the boost and attenuate controls work independently, you can use an old trick to add weight to the bass region while also notching a bit above the cutoff point, by boosting and attenuating at the same time (try it on your kick drum and you'll never look back). On the high-frequency side, you can set separate ranges for the boost and attenuation. Said another way, you can boost at 12kHz and cut at 5kHz, adding air to a track without increasing presence.
Vintage solid-state classics
There were solid-state Pultecs? There were, indeed. Introduced in the 1970s, these equalizers sported tighter bass than their tube counterparts and surprisingly sweet-sounding highs. Today's solid-state Pultecs, like their ancestors, employ API 2520 op-amps (rather than vacuum tubes) to drive their make-up gain stages. Otherwise, they're functionally identical to their tubular brethren. If you love the Pultec sound, but the characteristic low-end bloom of the tube units is a bit much, the solid-state models - including Pultec's 500 Series modules - will serve you well.
