Pultec EQP-1S3-SS Program Equalizer - Solid State Version

Classic passive equalizer
MFR# EQP-1S3-SS (API2520 Gain Stage)

Product Description

In the early 1970s, after condensing the classic 3U model EQP-1A into the 2U form-factor model EQP-1A3 (same components, same specs), Pulse Techniques introduced a solid-state line amp version of the EQP-1A3. These units have exactly the same front end (input transformer and passive EQ section) but utilize a solid-state opamp (API 2520) gain stage driving a Triad output transformer, just like the originals.

Like the EQP-1A3-SS, this solid-state version of the Pultec EQP-1S3-SS (which adds 1k & 2k peak boost & 5k and 10k HF shelf boost to the EQP-1A3-SS) is actually preferred by some engineers for certain applications (kick, snare, bass, piano, etc.) and also serves as the core for our 500-series EQs. Many users of this version of the Pultec describe them as “more punchy” and having “a tighter low end” than the tube version. Pulse Techniques, LLC is the only company licensed to use genuine API 2520 opamps in their products. These EQs deliver plenty of the punch and mojo of their tube-amp counterparts, with just a slightly different flavor.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
