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.

Great compressor!

I have been super impressed with True Dynamics so far. Like all plugins it takes a while to learn the sweet spot, but this one adds a real depth when it's dialled in. Great work Kazrog team!
