P42 Climax Line Amp


Pulsar  Modular P42 Climax is an innovative multifaceted powerstrip for tone shaping/coloration, saturation and conjures more of the idea of working with hardware. 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!

Don’t underestimate the few parameters in P42 Climax.  It is 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.

Don’t get scared by the price tag- a comparable hardware unit for a single channel costs around $1,700. Check the Audio examples below as we compare P42 Climax plugin tone shaping against the Neve 1080, Studer A812 Tape recorder, WolfBox DI and other hardware devices.

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.

How do you get the Motown sound?  You will need the Wolfbox DI made in the late 60s and used by the recording studios at that time for the signature bass guitar sound and the soft electric guitar sound. The Wolfbox was driven by a Triad A-11J or A-12J, which are not produced any longer. This is what drove the legendary Motown sound. It’s the sound of James Jamerson, Dennis Coffey, Robert White, Joe Messina, and the Funk Brothers- Motown’s legendary in-house rhythm section.

P42 Climax extended functionality is able to nail the sound of a Neve 1080. The 1084 is one of the most revered hardware units ever designed. It sounds like a 1073, and it gives you that beautiful Neve sound thats so sought after.

    So simple to use yet the sound quality is excellent. Important part of my mastering chain.

  2. Victor Jacquemont

    It’s amazing.

    I’ve been using the P42 Climax for 4 months now in the studio, and I think it’s ended up on every track that’s been done. It’s a fantastic bit of kit. Very low cpu usage. The new GUI is great. And (for me) what’s most important is the sound, and oh boy does this deliver! It’s amazing! and sound/tone shaping is just so flexible & easy. I’ve heard some people say it’s expensive. Well it isn’t cheap, but then again what top quality items do come in cheap!?!? IMO It’s well worth it. It sounds like great hardware to me, and It puts a big smile on my face. You really should check it out.

    I’d been searching for the perfect saturation plugin to add some weight in mastering that sounds convincingly analog but has the flexibility of digital.

    Even at version 1 P42 was better than anything I had ever tried and from the first moment I tried it in a mastering chain I knew I was going to be using it a lot.

    At version 3, the flexibility is all there. Switching in or out filters, a bit of shelf filtering an improved airband and gain compensation.
    For mastering I tend to be very gentle and it definitely lets you do that, add just enough seasoning but not destroying the flavour of the mix. There’s been a couple of masters where all I’ve had to do is combine it with one EQ and a limiter and the artists have loved the results.

    In mixing it can work in the ‘pre-amp’ role, making digital synths sound more analog, and even making very linear analog synths sound fatter. I’ve also used it to really saturate a drum buss, with glorious results. Amazingly it uses so little CPU you can afford to use it everywhere.

    Check it out, you won’t regret it.

    This is about as good as it gets for saturation and more. You can very quickly and simply dial in a great, robust, natural sound. It’s incredibly expensive, but I just could not pass it up! It is cpu friendly and worked well enough on my 2 bus to make it worth my while.
