From the SoundToys website: “Little Radiatorâ„¢ gives you the warm sound of the classic Altec 1566A tube mic preamp, and it’s totally free (for a limited time).”
Super cool.

From the Elysia website:
“Its main function is to change the proportions between high and low frequencies. The principle is quite similar to a pair of scales: Dependent on the gain setting around a variable center frequency, the high frequencies are boosted whereas the low frequencies are attenuated (or vice versa) at the same time.”

8 free plugins. Not just one; 8!
Blue Cat Audio has a bundle of free plugins available for download that include:
Whether or not they will be useful to you is really up to you, but at the price (FREE!) they are definitely worth a try.

Yet another “amp simulator”, but a fairly decent one. Simple controls (just like a real amp) and… it’s FREE! Useful for more than just guitar as well (vocals, crushing some drums, etc). A must have, in my book.
(Did I mention it was free?)
The De:Esser is exactly what it says, and what you think it is.

Limitations of the freebie:
All of these limited features of the free version are available in the full, paid version, which at the price ($79) is really worth it. It still works great as the demo, though, which is why it is listed here.

A free, band limited version of the EQ Rangers. Definitely worth a look/listen, though you may find yourself hooked by this “tease” into buying the real deal.
From the Flux website:
“Turning the central button on the sweet side, decreases the transients amplitude. On the bitter side, the transients amplitude is magnified. Bitter-Sweet also features a control for the signal to be processed. When the main position is engaged, the process affects the stereo signal. If Center is engaged, only the M signal of the internal MS matrix is processed. If stereo is selected, only the S signal from the MS matrix is processed. Three transient detection modes can be selected. A varying period of integration for transients can be accessed. A Link function is available to compensate the output gain regarding the transient processing setting.”
