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.

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.

    Great with vocals Motown preset is awesome.

    Absolutely incredible sounding and fast to dial in. The fact that the code is so magical that there’s next to 0 CPU hit is simply mind boggling. I’ve got saturators that TRY to do what P42 does in which one instance of them takes 30% CPU hit. P42 is the best saturator on the planet currently bar none.

    After using P42 – Pulsar for more than a year, I can absolutely confirm it’s the best most natural sounding saturation plugin I’ve used.

    It’s my go to plugin for saturation.. The weight it adds to a mix is amazing, but without being harsh..

    BUT – when I heard about the MOD additions, I initially didn’t think it would be worth it. I haven’t typically used the shelf EQ, even though they sound good, I didn’t have a place for it.

    I did test it though, and I tested it quickly on a client project.
    There were some elements that needed just a slight boost to enhance ~700hz.. I’d got a good result with another well known colour EQ plugin… I did quick try with the new MOD proportional EQ and dialled in a much better result, much faster.. So, I bought it on payment of the very next invoice..

    Playing around with extreme boost I found it to be altogether pleasing, although not something I’d use in mastering, it would be fantastic for mixing.

    So if you are a new user – it’s well worth the whole package.

    If you are an old user, try the proportional Q.

    Great sounding and, importantly, very quick and easy to use plugin. Excellent for general tone shaping.

    This plugin lives on my mix bus and has really added something lovely to my tracks. I was looking for something to bring that analog “aliveness” to my mixes and demo’ed the P42 as well as a few different Pultec and Massive Passive style EQ plugins. The P42 won the shootout and was an instant buy for me. I just use a subtle amount of saturation with the AIR setting activated and set to about 8K and it’s fantastic. I haven’t even tried this plugin for shaping the tone of individual tracks and busses yet but I’m sure it will be fantastic for that as well. I highly recommend the P42!
