Makes a difference

I purchased the EQP a year ago and have found it to be a great addition. I was looking for an eq that I could use for tracking when necessary and found this pultec style eq to do the job very well. I run this with a Heritage Audio 73 which has two channels. After A/Bing, with one channel with the eq (in bypass and the second without), I found the channel with the eq to just have more character. Of course once you start using the eq features you will truly reap the benefits. I use it primarily on vocals and bass, Heritage 73>WA76>EQP. Just read in Mix magazine that this is the same chain Aerosmith used to track vocals and bass for Walk This Way. Only regret is not waiting longer for the newer units which have an attenuation feature but haven't had a problem without one.

Amazing, everything they've said is true

I bought a pair of the EQP by Warm Audio. The reviews in trade magazines were so over-the-top glowing and the price SO LOW I had to give them a shot. W O W is an understatement. I have a large Bose PA with eight 802 and subs, for fun we patched the EQP on the stereo outs and the results were amazing, it was like the soul of the bottom-end was awakened but never got mushy or blurry. I ran a 414 through an API 312 into the EQP and love the silky high frequency capabilities, it can get that "hooky" sound in the upper mids that only an inductor-capacitor based circuit can possibly achieve, sounds amazing on our female singer. In the studio I patched the EQP to my Neve 8816/8804 mixer stereo bus and the results were fantastic. I'm an old-old school recordist, definitely out of the box type, I'm gonna need several more of the EQP to run as inserts during mix down. Sweetwater made this even sweeter, great delivery, I get stuff faster than when I was in California :-)

Great value for the money !

I owned 2 vintage EQP1-A, I own 1 new Pultec EQP1S3 and 1 new Pultec MEQ5... I'm telling you.. buy this unit .. you won't regret it !!! Very very near to the originals for a fraction of the price. Build quality is also great.. and on the low end it's pretty spot on w/originals!

Fantastic EQ

Definitely recommend.. one of the best in market with its price.

Sweetwater Advice

Carson McClain

I recently went through some tracks I'd mixed on my computer over ten years ago. When A/B'ing them through the Warm Audio EQP-WA, I realized how lifeless and improperly EQ'ed the originals sounded. The Cinemag transformers in combination with the tubes added an extremely smooth, warm sound that not only gives me clarity I didn't know I was missing, but added an amazing, finalized, finished, mastered sound that is far more pleasing to the ear. How on EARTH did I ever live without this?

Cody Kraus

The EPQ-WA is my go-to equalizer for introducing a classic tube vibe to just about everything I record. Large knobs and stepped attenuators make dialing in the right amount of EQ quick and easy, and when I use other equalizers, the EQP-WA's bypass function still passes signal through its tube amplifier section, providing my tracks with the round fatness I love.
