Rule Tec EQ1A


Instant love. Sounds massive and punchy. Adding low frequencies making explosions from kick, yet retaining all the transients. It’s super easy for me to make an event from the bass. Really love the smooth top end on vocals. Now it’s all over my mix. From kick, bass and vocals to guitars, keys and plucks. Classic eq with modern character.

Producer, Mixing-Mastering Engineer

Overall a perfect Pultec Channel-strip that has all you need for equalizing individual instruments as-well as full mixes. You really can't go wrong with the Rule Tec Heritage Pro.


Producer, Mixing Engineer

I have the original machine. But this plugin is just like original. Even better than the best known emulation versions. My directly recorded vocal tracks turned into giant, definitive and clear voices. I definately recommend it! I use it on even electronic music...

Favorite Pultec clone by far.

The EQ1A is by far my favorite Pultec clone by far. Its so easy to make drums sound huge its like cheating.
- Steve M.

Easy To use and low cpu usage

Sound great! Easy To use and low cpu usage. In my experience, this is the most beautiful pultec model
- Lorraine T.

Thank you so much Noiseash...

Great plugin even though it's a EQ it actually give my drums punch like a compressor. One of the best investments I've made. Thank you so much Noiseash...

Oh yeah! This is exactly what I need!

Great plugin. Very CPU friendly. Adds that famous Pultec shimmer I sometimes need. I’m no Pultec expert but I’ve seen/heard this EQ do things even Filter Pro Q can’t do and I like to use them together. For example I dial in what i can get from the Pro Q and then maximize that with the Pultec shimmer. Other companies make their version of this and I haven’t tested them, but I dont’ like CPU-hogs, and I can tell you that based on my research this plugin seems to be the best value for the money and possibly the most CPU-friendly version of the famous analog EQ so many desire. As soon as I tried it I said “Oh yeah! This is exactly what I need!” It really gives you a beautiful top end that’s hard to get anywhere else. I plan to use this on many mix buses.
- John M.

Yummy bass and treble sounds

Yummy bass and treble sounds. The best mastering eq. Also the best choice for the kick, bass, vocal and guitars...
- gianni k.

Love it!!

Super ! Easy to handle! Superb for mastering.
- Eddie Y.

Sounds amazing

So far I’ve only used this on drums and it sounds amazing. The boost and warmth it adds to kick drums I’ve been unable to achieve with any other plugin. Can’t wait to try it on other instruments!

Seriously impressive!

Seriously impressive! Inexpensive or not, this sounds amazingly smooth and has that warm mojo in the mid range I look for in a Pultec

- john c.

The best

The best emulation, highly recommended.
- Matthew C.

The feeling its definetly analog

I really don’t like having hundred of plugins, I prefer having few and master those. I use Logic and the stock ones are very good. They even have an emulation of Pultec but after seeing a lot in youtube comments the Rultec, I wanted to try : with this guy, when you crank the bass boost, you really feel it, in a very pleasing way. I dont own some hardware unit so I cannot compare, but the feeling its definetly analog with this plug. And that for not even 30€ !!!My friend who only use UAD is also conviced. But get a demo and try yourself !
- Täd B.

An excellent emulation

Súper Perfecto

Rule Tec - it is excellent!

Add the perfect touch of brightness and very sweet bottom low end! it is excellent!
- Babajide B.

another awesome eq

bought this while it was on sale. I'd wanted it bc it's based on classic tube gear. This one has a weird layout that's hard to learn, but I've got my sounds dialed in. I'd like to see more presets, though. It would provide more insights re what to do with a given sound source.
- theo y.

Definately Phenomenal

I’d pay the 10 price for this plugin alone. Just amazing model, like the real one I have. Definately Phenomenal

Perfect for noobs

Eases things up a lot!
- Valery D.


Analog perfection. It adds a great saturation that makes the tracks sound like harware recorded. It also adds so sweet bottom line. Just great!!!
- nino d

Transformation to real analog

Transforms the sound to big huge analog tastes. I really love it. I use it on everything (tracking, mixing, and yes, mastering) when needed.
- Hiroaki N.


OMG, now I call that Analog Saturation and Real Emulation. Awesome.

Real Pultec sound

Real Pultec sound. Great for getting that 70's and 80's rock vocal or bad ass drum. At first it was lacking finness in the top end but I found myself reaching for it more and more. It just has a thing.
- Zachary W.

Another fabulous Noiseash plugin!

A great realistic analog equaliser that allows you to get exactly to the frequency you want with utter ease. Another fabulous Noiseash plugin!
- paul m.

One of the best colored plugins

If you want to add some sauce to your mix this is the way to go
- Reid P.

excellent! yep, that did it.

Really impressed with this plugin, the include presets are fantastic and cover a wide range of styles. I have been trying to catch my hardware Pultec sound and have never come close to these. Wish I’d found this sooner and saved myself a lot of money in the process. excellent! yep, that did it.
- glen d.

One of my favorite eqs

Perfect tool for mixing and mastering

The perfect tool for mixing and mastering. A real deal for me. Adding analog tone with a sweet brightness and bass is so great with this pultecs.

Color the emotions out of the music

Amazing EQ. I am verry happy to live in the digital age and also have the possibility to ad some warmth of the past. This EQ is helping to color the emotions out of the music. Especialy on master track, kicks, guitars, bass, vocals and solo's.
- Ralph B.

Super usable

It sounds great on anything, quick EQ, preamp with some nice sounding gain and it really helped that I got it at a very nice price. Super usable. It´s one of my go-to plugins when I need some extra warmth.
- Enrique M.

The Lover of the tracks 🙂

Like all other pultec models, this one is a must have for a professional engineer. It touches the tracks and the tracks are never be the same again. They are beautiful now! Tracks love this baby 🙂

Top quality go-to plugin

Top quality go-to plugin for tone sculpting. Watch the demo vid, get your tone with the boost knob. bring up the cut knob to taste and tweak with the bandwidth knob. Every position on each knob yields a musical, usable eq. Immediatly added to my mixing chain for drum bus, vocals, piano & guitar

- Daimler P.

Absolutely LOVE it!

- Mikael H.


Top end, bottom end, and a nice, warm mid. My mixes have never sounded so good. I hadn't even planned on buying the Puigtecs right now, but when I saw them listed in my daily deals, I couldn't pass it up. They are MAGNIFICENT EQs.

Required for mixing and mastering

Very user friendly. Rule Tec Includes all plug-ins required for mixing and mastering.

Awesome plugin

Awesome plugin. Allows you to get at any frequency you need to, not just to boost but you can out that notch to fit another instrument in its own space.
- Ricky W.

So satisfied with it, Real Deal.

I could make it sound similar to what I recorded with an analog pultec rack. I am very satisfied with it, and I will continue to purchase other plug-ins based on sale products.
- alper s.

Sweet bottom

I love to use this plugin on drum busses. Really adds a nice quality & sweet bottom to the sound. ..... timberline
- timberline c.

Perfect Bottom

Do you need more presence, clarity or a bite mark as well as the Perfect Bottom? Just grab the Rule Tec and crank it up!
- brad f.

My new first EQ

I used many Pultec emulations. but this one satisfied me the most greatly. Especially on Pultec trick and treble transients. ...... It's my new first EQ now
- Patrick A.


I don't know how this compares to the original outboard equipment, but this Pultec just sounds great. I used it on a drum buss and it kicked!
- Per-Erik C.

The power and clarity is awesome

I suggest making sure this plugin is added to every mix. The power and clarity is awesome....
- Mark C.

Finally someone gets it about Pultecs !

I am not a huge Pultec users. In the studio I am used to having "only" 2 Pultecs units. But I tried all Pultec EQ I could find and was never really happy with them. Because of one thing : The way they handles transients and peaks. This Pultec gets it ! Finally a Native Pultec that has that very nice low-end reinforcement and respect to the transients. I def recommend it. It lives 95% of the time on mixbus for my in the box mixes now. Awesome job !!
- Wheeliemix

Well worth

Sounds great, easy to use, adds to almost anything you use it on. I even put it on a frettless bass part which turned out great. On bass drums works great too, for eny genre. Well worth the investment
- Douglas C.

EQP1A is one of the best classic eq in the world. But that model, is the BEST EMULATION MAN!

All over my mix

Instant love. Sounds massive and punchy. Adding low frequencies making explosions from kick, yet retaining all the transients. It’s super easy for me to make an event from the bass.

Great definition

The high end has a great definition but at the same time it remains so smooth. The lows feel big but at the same time feel controlled.
- Jay R.

Like Original

I have the original machine. But this plugin is just like original. Even better than the best known emulation versions. My directly recorded vocal tracks turned into giant, definitive and clear voices. I definately recommend it! I use it on even electronic music...
