The op-amp that put punch and harmonic density on decades of hit records. The boost-and-cut behavior engineers discovered by accident. Fairuz takes both and pushes them into territory the original hardware never offered.
Turn a band off and the op-amp stays in circuit. Get the harmonic color hardware EQs only deliver when you boost hard — without drawing any EQ curve at all.
The classic trick engineers replicated for years using two filters on the same frequency, made into a single band. Focused boost, automatic complementary dip, no congestion.
Voice input transformer sets the tonal stage. Hammer output transformer adds body, density, and saturation. Drive shapes the tone before the EQ ever moves.
Every band runs through a real op-amp stage — voiced after the discrete circuits that defined what an EQ could do to a sound, not just to a frequency. Push it and it gives back warmth, density, harmonic weight. Back off and the signal stays cleaner, more transparent.
That character is always there, whether you're sculpting frequencies or not.
Push Fairuz hard: bold Contour boosts, full Hammer drive, op-amp saturation across every band. Then blend it back with MIX to taste. All the character, as much or as little as you want.
The Contour bands take the boost-and-cut trick — the one engineers replicated for years using two separate filters on the same frequency — and make it a single band. One move.
Four op-amp EQ bands, three shapes per band. Surgical when you need it, broad when you don't.
Gentle boosts stay broad. Large boosts focus automatically. The Q follows the gain — exactly how analog EQs behave.
Stepped points chosen by ear, with deliberate gaps that avoid problem zones. Or sweep continuously when the source demands it.
An infrasonic circuit that establishes weight below 30 Hz before the EQ ever touches the signal.
Shelves with complementary dip behavior. Lift the top end and the upper-mid pulls back automatically.
Place the high-pass before or after the transformer. Different position, different low-end character.
Wet/dry blend built in. Push everything hard, then dial it back to taste in a single move.
L/R randomization for real analog imaging. Designed for buses and groups where width matters.
A great alternative resonant EQ! Combining transformer and voice controls with spectrum sweeping for pleasant—or ear-fatigue-inducing—frequencies often yields excellent results. I now often reach for Fairuz when traditional EQ or dynamic EQ just doesn’t do the trick. I also have a soft spot for the optional stepped controls, which is a classy addition!
Maybe add a horizontal version of the GUI? Otherwise - great!
What if PM made a 'character' EQ that could be many characters? As with it's older, wiser brother, the P440 Sweet Spot, the secret is in the unusual but carefully shaped curves and high and low pass filters. Unlike the P440 you have less fine grained control over every nuance, and less of a zoomed out mastering level perspective. With the Fairuz you get the curated options you get, let go of some control and are rewarded by workflow and using your ears. Trident A range users will be at home with the concept. The Fairuz can go from extreme to subtle but thrives when pushed in unusual ways, in unexpected combinations. Curve and parameter wise, there's nothing here the P440 can't also do (qualifier: each does "have a sound" and the saturation options are not quite the same), so there's a case for saving your coins. But even if you ultimately want both, the Fairuz often gets the nod on instrument level tracks. So, what about those many characters? The "voice" knob is key. Add it for some built in saturation. Remove if you want the creative workflow of those PM eq curves, while putting your own saturator or preamp plugin of choice before it. Sure, you could painstakingly recreate any curve using FabFilter or it's many imitators. And sure there's also a million and one "character EQ"s out there where you get what you get, but choose for the color. The value proposition of the Fairuz and what makes it unique is that it is something in-between: characterful curves with a slight mind of their own, that could have a color, any color, or none at all. Unlike many "character eq's" that trade on nostalgia, this sounds modern and it sounds great.
Lastly: a short mention of the presets. They're excellent. So many presets just offer the same redundant options ("drums" "more drums" ...) As if the only music ever to exist was made of drums and guitars. And you didn't have your own go-to moves for kick drum memorized. Presets should be for those things you don't always already have dialed in, but when they come up, dang it's handy to have a preset! The Fairuz has presets for cello (multiples of them!) as well as "bowed group" "plucked" various shadings of vocal options, piano, and even "lute/oud" If you mix classical, scores/soundtracks, world, folk, jazz this EQ is for you. But also it's fresh to try something left field on synth pads or that odd percussion element you can't get a handle on, having these options is refreshing and worth your time.
Very nice equalizer, with the PM magic. In addition to high, high mids, low mids and lows, you can use high pass and low pass filters, high and low shelves, tremor for frequencies around 30 Hz and below, blend with the dry signal and add a touch of color. Simple and effective eq. when surgical work is not needed.
I love the voice knob. Nice for enhancement.
High shelf is very sweet
P422 Fairuz EQ
I’m always on the hunt for color EQs that are truly vibrant, packed with features, and easy on the CPU. Surprisingly, there aren’t many that check all those boxes. So when I discovered Fairuz, it was an instant buy.
Fairuz does it all—it can be pristine and transparent, or richly colored when you need that extra character. It offers features you won’t find in other EQs, and its efficiency is remarkable. One standout for me is how well it performs as a mastering EQ, which is a real testament to its design and quality.
Simply put: this is an EQ you can use on everything.
Another hit by PM.
This EQ is highly versatile, and the saturation sounds excellent to my ears.
I especially appreciate the ability to bypass the EQ section while still using the saturation—such a useful feature.
Since the EQ curves can be quite unconventional, the addition of graphical displays was a very welcome update. It really helps you understand how each band is shaping the sound.
エミュレート元が無いPulsar modularオリジナルのトラックEQです。
中央のノブが周波数、ノブ右横のカーブスライダーがゲインになっています。
ゲインスライダーのステップ入力ランプを消すと、周波数を細かく設定できます。P450やP915より自由な点です。
P422はVOICEノブが特徴的で、一通り各周波数のゲインのし終えてから、VOICEノブを右に回すか左に回すかで、全体の印象を固くするか柔らかくするかを調整することが出来ます。再び各周波数のゲインを触ることなく音色を変えられるのがとても良いです。
What I like:
* It has a smooth, pleasing character that enhances the overall sonic quality without sounding harsh or artificial.
* The push/pull ear-tuned stepped frequencies are excellent.
How I use it:
* Vocals: I find the Fairuz particularly effective on vocals. It adds a pleasant warmth and presence, making them sit well in the mix. The EQ is gentle and musical, allowing for subtle tonal shaping.
* Acoustic guitar: It can enhance the natural warmth and body of acoustic guitar recordings. A touch of saturation can add a nice vintage vibe.
* Electric guitar: It works well for adding warmth and subtle grit to electric guitar tracks, especially for cleaner tones or bluesy overdrive.
* Bass: The Fairuz can also add some warmth and subtle harmonic richness to bass lines.
Perfect EQ to use if your looking for the feeling of an Analog console, you can use it to confidently boost frequencies and still sound natural and organic.
This EQ helps me across my whole mix - from the little touch ups to greater EQ shaping, it always sound soo 'right' to my ears.
This EQ is unbelievable!
I really love the sounds this EQ can produce. it is a gemstone!
The power of an Infinity Stone on any Track & Song the P422 Fairuz!
It is Top Quality & Sounds & Feels like Alchemy!
One of the best EQ plug ins available, can be surgical and musical. I thought I was over buying EQs until I tried this one. its truly special.
P422 is a terrific tool to have in the arsenal.
It excels on acoustic sources, as you can sculpt or enhance them without warping the spirit of their sound. The hammer circuit adds a very unique, almost mysterious flavor. It is subtle but it has this lovely grit and a helpful tightening effect. I really like pushing the midrange into it.
This EQ is truly extraordinary. Its combination of warm musicality and subtlety captures the magic of Pultecs in a totally parametric design. This really is one of those IQs where you con't realize how much better it makes things sound until you bypass and reengage it. And I say "things" because it works on everything! Pulsar Modular makes the best plugins I've heard and this is at least tied for the best. I don't know how this EQ came to pass but I love everything about it.
Another great tool from Ziad that allows me to get inside the mix and sculpt to achieve the sounds I hear in my head. Love it.
Love using this EQ for Vocals and everything else to bring out the best possible sound of what I'm working with. Using this with other PM plugins I couldn't ask for more. Just try it out yourself and see. Great work.
In my experience, PM plugins live up to the hype. The P422 deserves all the praise I’ve read on gearspace. It’s good, really good. I’ve used it everyday since becoming a day one early leaper and it’s been a joy to work with.
This is the only EQ I can remember that makes everything sound more "real" and more solid. Yes, other EQs make things sound good but on guitar or bass, P422 reminds me of having my ears down by the speaker; naked but better. A 9 dB of gain isn't harsh or even too much. Everything seems closer. If the sound you want is rude and raucous, this makes it stunningly more so. Amazing!
This EQ is really incredible. My favourite EQ from Pulsar Modular or any manufacturer for additive. I am pairing this with MDW-eq6, but if I had to only choose 1 EQ as my only one, it would be this EQ.
Congrats Ziad, I thought I was set with the P450, but I feel more connected to the P422.
great! great! great!
This is one of the easiest to use and musically superior EQs you've ever made.
In particular, LOW & HIGH SHELF works very well.
A very welcome addition to the Pulsar Modular toolkit. Can't wait to have the final version with the final GUI!
