The EQP-1AS is a stereo, fully stepped 1:1 replica of the most beloved Tube Equalizer in the world, the Pultec EQP-1A.

After retiring the MK1 in 2019 we spent the last few years developing new custom-made input, inter-stage and output transformers, as well as accurate Inductors to bring this unit back to life sounding as close to a vintage Pultec as possible.

The EQP-1AS uses six Sowter Audio transformers as well as five tubes including a 6X4 tube on the power supply famous for its “sag” on these units.

Sowter transformers, though expensive, far exceed any other offering when it comes to low end, sonic timbre and the unique frequency response that faithfully reproduce the tone of a vintage unit.

Aside from making an exact sounding replica affordable, we also wanted to make it size friendly and therefore decided to make a stereo unit in the same 3U classic faceplate with stereo controls. All switches are matched within a 0.1% tolerance and all tubes are matched for perfect stereo operation with fully stepped switches.

 

The EQP-1AS  is built with premium components

Utilizing custom Sowter UK Transformers, premium Carnhill Inductors, NOS tubes, Fully Stepped controls, Corner Dubillier Capacitors, Allen Bradley Carbon Resistors and Neutrik connectors, we have paid tribute to this legend and believe it to be the most accurate and best sounding recreation made today.

Each unit is handmade in Chile by us with great care and detail and goes through a 72 hour burn making sure these units will perform flawlessly for many years to come.

 

100% satisfaction guarantee – if you don’t love your EQP-1AS, we’ll refund you

If you’ve used an original Pultec before, we’re extremely confident the EQP-1AS will put a big smile on your face every time you use it, however, if you’ve never touched the original before, as gear-lovers ourselves we understand that the only way to really know if this compressor is right for you is to put it through its paces. That’s why the EQP-1AS comes with a 30-day money back guarantee. This allows you to get it into your studio and see how it impacts upon your recordings. If you love it (and we think you will!), great…keep the unit and create amazing music with it. If not, no problems. Just send it back to us and we’ll fully refund your purchase.

    I bought a pair of these bad boys. The bottom end on the Stam, was tight and punchy (no flubber) and resonated beautifully! The high end was silky and smooth, it was so pleasant to the ears. The sonics were deep and 3d, I love these units. Yes do believe the Hype, Stam stands up like a champion and most importantly I love what Joshua stands for in the market, these units were made with heart & soul, you can feel it. Best investment I made! Thank you

    Increíble producto

    Gracias Joshua van der Stam y Camila junto a todo el equipo de Stam Audio que está detrás de estos maravillosos productos.

    Es increíble la magia que tiene en las voces solo aumentando los 100 hz y los 10Khz, brillan! Y le da una presencia tremenda.

    Ni hablar de la tarola y principalmente el KICK!!.
    en TODO brilla esta unidad.

    Gracias por el rango de frecuencia medio lo amo igual 🙂

    I have a pair of Stam’s Pultec clones and I’ve already run two mixes thrum them as part of my 2-bus chain (Manley NuMu > Massive Passive > Kush Clariphonic > Pultecs > Gyraf G-Bus).

    The good: Compared to similarly priced clones of Pultecs, the Stams clearly benefit from the inclusion of the 3rd transformer stage (as per the original design). They greatly help to round over some of the top end edges that the Clariphonic creates to give a bright, but rounded, top-end. The other clones I’ve heard I’ve heard are less ‘warm’ and add too much edge to the top-end for a Pultec style EQ; at that point, I would rather go just the UAD route. I also love the refined purist route they went; including the third transformer stage, but also morphing in the mid-band control of the M-EQ Pultec!

    The bad: Took 9 months to fulfill the order, and a bit too many paranoid e-mails with customer service to keep up to speed. They also shipped to my old studio address despite my message to them that I had moved; however, this isn’t ridiculous considering that it was the address on the PayPal invoice. That being said, I can see the improvements that Josh is making to how the ship floats (rather than just how powerful the cannons are), so I’m very optimistic that Stam will prove to be an excellent company.

    Best of luck Stam! I’ll definitely have more purchases from you in the future!

    These EQ’s are well thought-out and faithful recreations of the originals. Bass magic attenuation? Check. Variable mid clarifying? Check. Beautiful high-end silly smoothness? Check. Two EQ’s in one, a fraction of the cost of a branded unit, and genuine, premium components. What more could you possibly ask for? I would have never afforded real Pultecs but I don’t feel I am missing a thing with these beauties. So glad I bought a stereo pair!

    I got my pair of EQP1A yesterday

    They look and work very good.

    My first test on the mixbus was completely convincing. Very good sounding units. Clear, warm and big. Everything works perfect. So cool to have the mid band with the cut/boost/bypass option.
    This is a big bonus !

    These EQs are very effective. (The same Setting on an UAD or waves Plug In sounds absolute dull. sorry for this unworthy comparison. but other plug ins are often more similar to the modeled hardware units)

    It feels like you can boost much more with these units without getting an exhausting sound. I am absolutely satisfied. Can’t wait to use them on my next mixes and for tracking.
    Thank you so much Joshua !
    Great work

    Awesome. Worth the wait. EVERYTHING sounds better through them. Only wish Stam would keep making them (or hope the make something similar) so more folks have the opportunity to have these.

  8. Menno Bakker

    Bought a pair of these with the NOS option and as match pair. Well worth the wait. Dailing in the highs is a party. These is great on the masterbus. Really really nice

    2 years after my purchase I still love my STAM EqP1A’s!!! My Music sounds 3D when ran thru these EQ’s. I have 2 for the Stereo Bus when Mixing But, I also use
    one on my Acoustic Guitar chain and one on my Vocal Chain while Tracking…They’re pretty incredible…
    I decided to upgrade to NOS Tubes in one and left the stock JJ’s in the other to A/B, Surprisingly the JJ tubes sound REALLY good…
    I am very pleased with Josh and the Crew and I now own 6 STAM pieces and Love all of them!
    (SA-87 Mic, 2x EqP1A’s, SA-4000 Stereo Comp, 33609 Stereo Comp, SA-312-T Tube Pre 500 series)
    WORTH THE WAIT, Plan on waiting 3 to 6 months for your stuff and you’ll be happy when it arrives a little early!
    Thanks to Josh and the Entire STAM CREW, I will be ordering another very soon!!, RK
