Soundtoys Little Radiator Is FREE Until January 2nd


Soundtoys offer the Little Radiator ($79 value) tube saturation effect as a FREE download until January 2nd, 2023.

Little Radiator is a lightweight tube saturation plugin by Soundtoys. It is based on the more advanced Radiator ($99) saturation effect.

The saturation algorithm is based on the Altec 1566A tube microphone preamp. It is a vintage tube preamp that was often used to fatten up the drums, especially the kicks and the snares.

Despite being a lightweight edition of another plugin, Little Radiator offers several advantages over its pricier counterpart. It is easier to use, features a streamlined user interface, and is cheaper. Even better, it’s currently completely free to download and use.

A quick look at the user interface is enough to understand how Little Radiator saturates the sounds in your mix. Use the Heat knob to apply more saturation and the Mix knob to adjust the dry and wet signal balance.

In addition, Little Radiator lets you apply a bit of noise to the signal with the Noise switch. This is useful if you want to emulate the subtle noise generated by a tube preamp. The Bias switch makes the signal more choppy and slightly lo-fi, which is useful for creative audio degradation.

Little Radiator also features a preset manager. The plugin comes with several presets that provide a good overview of the types of saturation and distortion you can get out of Little Radiator.

Here’s more information from Soundtoys: “If you want a touch of 60s warmth on your tracks, reach for Little Radiator. It’s great for fattening up bass, guitar, drums, or vocals. And it’s fantastic on electric piano.”

To claim your free copy of Little Radiator, use the coupon code HOLIDAYHEAT to apply a 100% discount to your order. The offer expires on January 2nd, 2023.

If you claim the offer, Little Radiator will be stored permanently in your Soundtoys user account (even after the offer expires).

You will need to sign up for a Soundtoys user account (valid email address required) to complete the checkout process and activate the plugin on your computer.

  1. Nope. I ‘m never installing iLok stuff on my system again. Ever.
    Nothing is indispensable anymore, there’s like a ton of choices and I don’t have to go through this.

    Happy November, everyone.

      With Little Radiator it took me less than 10 minutes and everything was set. What could’ve possibly discouraged you from using iLok License Manager? I’ve always found it quite straightforward. What are the downsides of it except having to remember to deactivate all licenses before changing OS or a computer?

      • My computer died and it’s impossible to retrieve lost license
        And you have to remember to deactivate your licenses before you:

        1. return to a restore point
        2. change/reinstall your OS
        3. change the name of your computer

        I’ve had all of these problems

        • Contact Soundtoys and they’ll sort it out for you. There is even a button in the iLok app that automatically contacts all the developers that hold your licenses asking for new licenses. I’ve done twice. It wasn’t immediate, but I have all my licenses back, from several developers (some took more and others less time, but all came through)

          Sometimes people just complain because they don’t know how to use the system.

      • I see your point.
        In order to install Studio One, for example, you download the installer, install the software, log in with your credentials and that’s it! Plus, nothing (literally nothing) else is installed along with the DAW.
        Now, in order to install and activate Pro Tools, for example, well,… Good luck with that. :-)
        It takes ages, a bunch of “3rd party” applications are installed at the same time, apps and services that run on system start up, slowing the PC down.
        So, since I just formatted my system, I decided to follow the KISS principle.
        Just a personal preference.

        Cheers to everybody.

    • I agree, iLok or any copy protection (except serial numbers) is off putting for me.
      For me personally it is a gentleman’s agreement, I do not use warez. I am 100% legit

    Thank you! I was thinking about buying Radiator so long but always came more important things. But now I can have his little brother. I think it’s enough for me. Very nice. I needed that sound.

  4. Radiator is one of the most analog sounding plugins I’ve used. The sound looses a little quality too, which is what old analog equipment does. It’s not for everything, but if you are looking for true analog vibe, this is it.

    Little Radiator reminded me about the issue with older versions of Softube’s Saturation Knob. Back then it was almost always necessary to use additional gain plugin in the signal chain for level matching. Well as much as I like how Little Radiator sounds, Soundtoys could easily improve their creation. Especially since there is plenty of space to implement a small output control.
    By the way even with the knobs set to default positions and NOISE, BIAS switches set to off position, Little Radiator adds plenty of low level noise. The most pronounced are low frequencies, where it reaches around -107 dBFS. Something to keep in mind if you’re like me and plan to use it on multiple tracks in various amounts.

      Make sure to maximize the webpage with payment options. Otherwise you won’t be able to see the bracket to enter the discount code etc. At first I thought there would be no way past the payment screen without giving all details.

  6. Awesome, thank you Tom, BPB, Soundtoys ✊
    I like this, it sounds nice, and its a nice winter warmer 😉
    I would say it needs an output knob like Michal says, but still is awesome and easy to use.
    Was easy to install from the single installer & I had the option of wether to use iLok or my computer to store the free licence, much appreciated, thanks again 🙏

  7. Thx but no thx. I was really happy to finally be able to use Soundtoys plugins as I heard iLok was not required anymore (and that’s the single piece of software I’ll never have installed again) and even wanted to purchase some of them. Unfortunately, that information is misleading or even false. Oh well…

  8. Well this is confusing. It’s asking for a license code/key but I never got one. I have the invoice in my Soundtoys account but there is no code anywhere.

    • Michal Ochedowski


      Your order of the plugin should be followed by an email from Soundtoys. Right after that you should receive another email, which contains activation code to be used in iLok License Manager.

  9. So I installed it, along with some PACE Wizard anti virus or something that came with it.. And now I can’t open my Waves Central app to access my waves plugins. It literally tells me to delete whatever antivirus may be blocking it and I’m certain this caused it. Pretty frustrating. When giving away free stuff, companies should be more like Delay Llama, just give me my install and we’re good lol
