Pultec EQP-1S3 Matched Pair Tube Equaliser
The Pultec EQP-1S3 two-band equaliser, a rare variant of the legendary EQP-1A equaliser, can give your tracks the massive bass, silky highs, and addictive warmth that made the original a studio standard. Pulse Techniques is back, building their classic EQs right here in the USA, without compromise or “enhancement” to the original designs. New Pultecs like the EQP-1S3 contain only original-spec components and are dead ringers for their vintage ancestors. It may sound like magic but it’s been time-tested and proven – the Pultec EQP-1S3 equaliser can make any track sound better.
Magical tools revered for their ability to improve the sound of audio simply by passing signal through them, Pultec equalisers like the EQP-1S3 are the stuff of legend. You’ve heard them on countless hits. Rare vintage units cost a pretty penny – if you can find one in good working order. So naturally, there have been many hardware and software “re-creations” over the years. Well, now you can grace your recordings with the sweet sound of the EQP-1S3: a genuine, made-in-America Pultec EQ.
Take a look at the Pultec EQP-1S3 and you’ll see it’s not designed like your typical equaliser. The two-band design basically gives you flexible high-shelving and low-shelving control, with a twist. Because the boost and attenuate controls work independently you can use an old trick to add thump to the bass region while also notching a bit above the cutoff point, by boosting and attenuating at the same time (try it on kick drum and you’ll never look back). On the high-shelf side things are similar, except 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.
What’s different on the EQP-1S3 compared to its brother, the EQP-1A3? There are more selectable frequencies on the high-band of the EQP-1S3, for starters. The equalization curves are also a bit different, and the low-band of the EQP-1S3 sports different frequencies than its brethren, giving you a different flavor while maintaining all that Pultec mojo.
