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. So I’ll get this out of the way first – these plugins are NOT cheap when compared to other plugins that cost less and also sound great. So why pay so much for this plugin? Simple – it sounds FIRE! There’s an ineffable quality about it that makes you want to use it on everything. I don’t know what algorithmic voodoo Pulsar Modular have got going on but it’s legit! Coupled with that, very much appreciate the very substantial updates that have been coming forth, thank you Ziad!

  2. I’ve had P42 for a few years now and it has only gotten better with the updates.
    I’m grateful that Ziad has not rested on his laurels and has continued to improve
    P42 making it indispensable to my work whether mixing or mastering. Thank you!

  3. A rather fantastic transformer emulation, tone shaper, saturator, color box, and a lot more. Sounds great, and the fact that it is so light on the CPU is the icing on the cake. Don’t sleep on the dual mono mode, either. It will make your ears very happy. Use it anywhere and everywhere. It’ll sound awesome!

  4. I just love P42. It is right now on all my channels and busses.
    Sometimes I just use the filters.
    But often I use more. Beautiful saturation and very nice basic eq. So I need much lesser eq moves later on.

  5. Simplify the best transformer saturation emulation out there. It’s not the cheapest option, but after 2 years I’m still using it on almost every single track. Amazing sounding shelves also!
