P440 Sweet Spot EQ


P440 Sweet Spot Mastering Equalizer audio plugin.

You have very likely heard words similar to the following uttered many times about mastering: “it makes the music come to life” or “it is the final polish that transitions into something breathtaking” or “It is like… magic!”. The wizardry lies in the hands of the practitioner of course, but surely, as all wizards wield an unassuming yet infinitely powerful device that is a conduit between their mystical knowledge and the physical world, so does the mastering engineer. To the wizard, it is the magic wand and to the mastering engineer, it is the equalizer.

Forget everything you have been taught about “High Passing” frequencies below 30Hz, and welcome to Sweet Tremor boosting infrasonic frequencies! Attenuate frequencies and you end up with a punchier and open sound! Boost frequencies and end up with sweet cotton candy all over your ears! Scream in horror when you check in Plugin Doctor the low shelf at 200 Hz or the high shelf at 2 kHz with a “stairway to heaven” graph, but then melt in your chair when you listen to it- like candy on a hot summer day. Nothing makes sense …visually but your ears tell you otherwise.

P440 Sweet Spot EQ will let you rethink what an audio equalizer can do. P440… your mystical magic wand.

Scott Weiser (AKA Jackal & Hyde)

Lunar Lander is INCREDIBLE! Realistic BBD Delay behavior.

Scott is responsible for some of the most head strong electrocore bass-bangers such as Dark Star, Go Bang, Beyond, This is the Sound of Underground and Bad Robot.

Marc Codsi

Extremely lush melodic plate reverb emulation. I use it when I want to add character to a sound.

Marc Codsi is a composer, multi-instrumentalist, record producer and film composer.

  1. A couple of months after I started using the P440 I posted a comment about it on Instagram saying I already used it on 90% of my masters. Ziad joked, asking why it wasn’t 100%. It’s close enough to that now.
    Both ITB and analogue mastering starts with this in the processing chain to set the (elevated) tone, and some tightening and clearing. Even just the Transformer options, the HW varieties and Soul (+ more rarely O2) give the music a unique send-off into the rest of the processing. Indispensable.

  2. A very interesting EQ / toneshaper that has made its way onto several masters. Spend some time getting to know it’s nuances. It is very different and deeper than initial appearances would lead you to believe.

  3. Great Product!

  4. The p440 eq is a special one. Clean but gives body to the sound. It’s certainly not easy to use at first but once you get the hang of it it opens up many possibilities. Don’t mistake this with a regular digital eq. Tremor creates a nice cohesion with the ultra low frequencies and the low body of the kick. Tibo adds saturation exactly at the spot you want with the help of the bias knob. The shelves are also helpful in achieving the right amount of heft and sparkle.

  5. Though it is not very easy to use at first, this is the best tone shaper with density, mojo, vitality but cleanness. Add to that, it’s incredible that it could be dealt with exceptionally low CPU usage except for OS/Soul on. Moreover, I like its GUI, however hope it should be get better visibility….
    Well their products are certainly expensive but low costs. Want to buy other theirs in near future.
