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.

  1. Throughout the past year, P42 Climax has found its way into countless of my projects. It sounds great, uses delightfully little CPU, and can add ‘that little something’ onto pretty much any sound source with a few clicks. As a saturator, it is easily one of my favourites, and its filters add enough versatility for it to find its place on many tracks regardless of whether the colouration one is after is very subtle or something stronger.

    Mind you, while it is relatively versatile, P42 Climax does not offer as many distinct styles of saturation as some of its competitors. So if you’re looking for a one-size-fits-all saturator with tapes, fuzzes and various circuit emulations, you may want to look elsewhere. That being said, the one style P42 has, does sound very pleasing to the ear, and often enough I haven’t felt the need to use anything else for my saturation needs.

    There is also no denying that the plugin’s quality is reflected in its pricing, and it is not cheap by any means. Still, if you can make the investment, I’d say it is worth it. But as always, since these things are subjective, I recommend you try the demo first to see if it’s a good fit for you.

    I have enjoyed using it a lot, and since it is one of the few saturation plugins on the market that can do very subtle saturation very well, I imagine it will be a favourite of mine for many years to come.

  2. If you don’t spend money on advertising and marketing, where does the price tag come from. Make your product more affordable. Or give the opportunity to buy in installments like LiquidSonics did. A 25% discount is ridiculous given your price tag. Not everyone is ready to give that amount right away.
    Great product though!

  3. I was very skeptical after watching several Youtube reviews and not hearing much improvement in the demo sound. I downloaded the demo of the plugin last week and it really sounds amazing! It just brings a track to life! You notice it especially when you have it on and then bypass it and everything falls flat without it. Detail is kept while adding a really nice saturation! Highly recommend!

  4. I like the P42 Climax. I compared it with other similar plugins. I think the difference is how easy it is to get a great sound with P42. With few adjustments, everything sounds good. Also noteworthy, is the fact that the plugin is CPU-friendly. Is the amount charged fair for these attributes? I think not; but then it’s up to each one’s pocket. For me, who live in a country with a devalued currency, the acquisition was very difficult.

  5. So apparently there has been some “controversy” with this developer pertaining to his pricing structure and not wanting to bend to the common thread. This type of attitude is very much show cased in not just the P42 Climax, but as well as LunarLander and the sleeper – the P914 FFB. The developer takes the approach of creating professional tools at, a professional price, but a very generous non-crippled demo policy of 40 days.

    I’ll keep my review strictly to the P42, pricing controversy aside.

    Sound – hearing the evolution of the developer take a hands on approach to modifying the original design from other user reviews put this as a strong contender for daily tracking, channel work, or even on the master. Due to the generous demo period, non crippling audio dropouts or inability to save allowed me to really dig in and hear the alterations of the plugins development based from a lot of positive user feedback. I

    Once the ability to remove the HP/LP made me realize this can be a first insert tone shaper that doesn’t coat the sound in harmonics but becomes apart of the sound.

    There are many other excellent tonal shaping tools that I own (Kelvin, everything by Fuse, and many others), this can be used on every channel and actually when place as the first insert everything else down the chain generally operates better from a sonics perspective. The tonal shaping qualities really don’t leave much to be desired and can enhance, tame, dampen, or blow up (in a good way) pretty much any type of musical, atonal, rhythmic, or percussive sounds.

    The price tag you’d expect something that doesn’t sound like “fake harmonics” or a basic waveshaper, you expect a professional useful tool that you wouldn’t hesitate on using for anything you can throw at it from demos to well funded commercial projects.

    Speaking of speech, this is excellent on dialogue and vocals. Overdrive/distortion really either shines or falls apart concerning the human voice, the P42 holds it together.

    GUI – Compared to the other product offerings it really doesn’t feel like it fits from a graphical perspective and seems a bit gimmicky.

    Personally can’t stand things that take up precious real estate, and on the other token tools that don’t have any form of graphical user interface are just as obtuse. If you look even at the knobs of every other offering (the P914 and LunarLander) they’re beautifully done and compliment each other. Looking at the P42 the GUI in no way shape or form reflects the sound quality. Everything from the fonts, color scheme, the faux transistor graphic, to knobs that have no universal theme of values makes it very difficult to get to the point of initially learning the tool, and in use. I think the developer should stick to the theme and vibe he has going from his other product line (since they’re much better done). Considering the LunarLander’s GUI is awesome and completely conveys the visual aspect to the sonic shaping aspect.

    Overall – From a generous demo period, no compromise on the sonic vision, but still takes user feedback seriously, this is a developer to support. Professional tools may come at a professional price, and to the pearl clutchers on price that secretly love the sound but can’t afford it (I know times are tough for some of us), save your pennies or use many other available tools. Because not owning this won’t prevent you from making an amazing sounding production, it’s just that using this makes it a heck of a lot easier.
