P42 Climax Line Amp


Pulsar  Modular P42 Climax is a line amp emulation for tone shaping/coloration, saturation and conjures more of the idea of working with hardware. Scalp 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. P42 Climax can conjure all the subtle non-linearities distributed throughout the signal path of  the assimilated device with its few parameters. Our signature LPF  gently shave the sharp, harsh transients and convert them to pleasant harmonic content without sounding dull. The combination of the HPF  & Low Shelving EQ will bring that “oomph” to your low end without mudding the sound.

Don’t get scared by the price tag- a comparable hardware unit for a single channel costs around $1,700. Pulsar Modular does not release a product if it is not in par or better than its hardware counterpart.

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.

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.

    Again … an expensive buy but due to the quality of the former bought plugins from Pulsar Modular I bought it blindly. Man. It leaves all other simulated line amps in the dust. Can`t tell what happens here. But if you hit the right settings, it`s like someone pulled the curtain from your sound. I formerly just know this from using my original Neve 1073 Hardware. Love it.

    I cannot praise this incredible plugin enough!!!! It’s like a magic dust of sonic genius!! seriously, you have to hear it to believe. I’m kind of hoping not many people discover it so I have a secret weapon in my audio arsenal that will be at the forefront of everything I produce / mix & master!! Hats off to you Pulsar!
