P42 Climax MOD


Pulsar Modular P42 Climax is an innovative multifaceted powerstrip for tone shaping/coloration, saturation and conjures more of the idea of working with multiple pro-grade audio hardware units. P42 Climax begins with the heartbeat of a hardware line amp, and ends on every single track because it has the cpu coverage to do so (more than 300 instances in a single session). Sculpt your perfect sound whether processing a single instrument, grouped tracks, the 2-bus or even when mastering. The sound is simply… unbelievable!

P42 Climax is a chameleon like, able to assimilate many different coloring hardware devices, but never intended to copy any single one! P42 Climax works magic on drum bus, snare, and of course the bass guitar. Inserting P42 on the 2-bus track, immediately opens up your mix and exposes hidden gems in your mix. With its Mid/Side processing and detailed metering (peak, RMS and LUFS) and Auto. Gain Compensation workflow, P42 fits nicely into your mastering signal chain, making it an essential tool to most Mastering engineers around the world.

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 very nice plugin for in-the-box mixing – P11 Climax MOD gives more strength to the mix without overdoing the mix, helping things feel sound more natural and bringing top professional studio level results.

  2. No plugin out there is as tight and focused at high levels of saturation as P42 MOD (and I’ve tried all of them and have been doing this at a professional level for decades and also own tons of analog outboard gear).. The fact that it has God-mode analog sounding saturation while still being beyond tight and hyper-focused with such a light CPU hit even running internally at 384 kHz oversampling is beyond insane. Add the proportional eqs & shelves and its just crazy; sculpting and tone shaping every sound in your entire mix with ease before hitting your main eq on each channel its like analog in-the-box heaven. The P42 is an absolute work of art programming-wise and a must own sonically. Any pro sound engineer without P42 MOD is seriously asleep at the wheel.

  3. When I first started hearing about P42 Climax I was reluctant to demo it as I already had just about every other saturator and it was a bit of an investment especially with the Australian Dollar exchange rate. I had seen too many of my previous high end plugin purchases from other vendors lose 90% of their value and become almost unsellable so I took my time evaluating P42 before I bought it. It is reassuring that Pulsar Modular has thought about this aspect as well and has a pricing system where your investment is protected and may actually appreciate.

    A lot of hours have gone into developing and perfecting this beauty and it shows. This one plugin goes a long way to getting a great sound and provides excellent saturation, EQ and filtering. The oversampling then takes it to another level. If I was only allowed to use one plugin for mixing and mastering it would be P42 Climax.

  4. Considered as another saturator, P42 quickly became the first plugin in a mixing chain that is capable of HQ saturation, distortion, tone shaping, filtering and stereo-processing. At first, I didn’t want to spend 200+ Euros for a single color box, but every custom chain containing 3 to 6 plugins, almost every time, sounded less existing and polish than P42. Tried to replicate throughout the year without much luck. Essentially, it’s “betterizer” where the whole is greater than the sum of its parts. EQ curves sound smooth, saturator always adds new dimension to sound without any breakup. Filters are nice, air eq sometimes can be really helpful. It shines at the beginning of the mixing chain or at the end of it. It can be used on group buses and master chain. What’s even more impressive in exchange for expensive hardware sound, P42 uses almost no CPU! from 0.5% to 1% for one instance on my old Intel Core i3 8100F.

  5. Another PM product I use in every production working on since I got my hand on it. Great stuff, thank you Pulsar Modular!
