Warm Audio Built Several Grand’s Worth of Classic Pultec EQ into an Actually Affordable Package

Pultec EQs are the quintessential several-thousand-dollar pieces of studio gear that cause head scratches amongst the casual. The thought of dropping on an equalizer the kind of cash the could easily purchase a fairly legit used car, when a similar plug-in replica can be had for a couple hundred dollars? It’s not a rubicon that is easily crossed by any but the most picky of audiophiles.


But it’s not solely plug-ins that stretch out their arms to those of us with grandiose dreams and duct tape wallets. No, there is the ever bountiful wellspring of redemption for the analog-first crowd: replicas. Warm Audio, already makers of some very fine “inspired by the sound of” gear such as the WA76 compressor, have tried their hand at recreating a Pultec-style EQ at a sub-$1000 price point. Very sub, in fact, as the EQP-WA will list for $699 in the US.

Now if you’re unfamiliar with Pultec EQ you may be thinking, “wait, I’ve heard that these are passive.” And I think most of us can agree that it’s easier to work with a passive EQ (which can only cut and not boost the signal) if there’s makeup gain at the end. But don’t fret: there’s tube amp in the chain for just that purpose. Will Warm have one of these units at NAMM in a couple weeks so that we can hear one in person? Let’s hope.

Warm Audio doesn’t have any product info on their page as of yet, but a company rep was going into detail on the specs and features of the EQP-WA on this Gearslutz thread, if you’d care to peruse it.

  • I’ve honestly heard some good things about their 1176 clone. You’d think for the price point, you’d be getting some sort of Behringer-esque piece, but I have considered getting it at one point. I believe some parts are Chinese, but they’re still manufactured in the US. But then again, I’ve been having quite a lot of fun with some cool Symetrix comps/eqs I got. Please let us know if they’re at NAMM! I’d love to hear a video.
