True Dynamics - Vintage Variable Mu Compression in the box

3 rare vintage tube compressors - available in plugin format for the first time!

NAMM TEC Awards Nominee

True Dynamics (nominated for a NAMM TEC Award) emulates the Presto 41AITA LA1B, and now (in version 1.1+) the Collins 26W - three of the most sought after and hard-to-find vintage tube compressors in all of pro audio. These are the rare secret weapons of some of the world's top mixing and recording engineers, and now they can be in your DAW for a tiny fraction of the cost of owning the real units (assuming you can even find those!)

The emulation technology behind True Dynamics incorporates the same industry leading analog-modeled DSP behind Kazrog's renowned True Iron plugin.

Simply Magic!

I bought True Iron, and was amazed. So in light of this, I just bought True Dynamics, and simply love it (or them - (all those compressors))
I always use True Iron across L&R outputs on every mix in various DAWs, and always on some tracks in every DAW.
Highly recommended.

But back to True Dynamics.
I have very many software compressors, (and loads of corresponding cash investment) but True Dynamics in comparison to others is much cleaner, significantly warmer, and more 'musical' than anything else.
It has a wide range of truly great sounds, it's powerful, and is very easy to use (and to buy and install).
I can't praise it more highly. I sincerely wish I had found and tried Kazrog products a long time ago.. (and saved loads of money)

Three great compressors

These are my new favourite compressors. Each one has its own character, a sound you hear even without any compression. I've used Acoustica Audio plugins for years, and I have access to UAD plugins. In my opinion these Kazrog compressors are definitely at the same level of quality. And way above any Waves compressor I own. Highly recommended!
