True Iron – the true sound of transformers

Add warmth and heft to your tracks and masters.

NAMM TEC Award Nominee 2020True Iron is a NAMM TEC Award nominated plugin made by Kazrog in conjunction with Devin Powers (Powers Music Company). It accurately emulates 6 classic line transformers, known for their use in many of the biggest names in vintage analog outboard sound processing. Models are based on the UTC 108 X, the Malotki E4M – 4001B, the Western Electric 111C, the Haufe V178, the Marinair LO1166/A , and the UTC O-12. Bonus: Take a look behind the scenes at the gear (and producers) who inspired True Iron.

These transformers add weight, heft, and girth to your mixes and masters. The plugin features adjustable strength, input impedance, wet/dry ratio, and a special “Crush” control to add fat transformer saturation to tracks and buses. Plus, the CPU usage of the plugin is low enough that you can add it to every track or bus in a mix for added virtual analog warmth across your entire mix.

You need this!

Missing the warmth of transformers in your digital workflow?
-You need this!!! Worth every single $, and it's cheap!


I am a broke college student going to CSULA studying production and songwriting and I just wanted to say thank you for making this plugin!! I am scrambling to find 40 bucks that can spend on this but in the meantime I just wanted to say thank you for making something so inspiring and useful. I have the sound toys effects rack, but those arent suttle, the UI can be distracting, and most of all you have to run it at 96k to get it to oversample and open up the plugin. This is exactly what I wanted and needed so just thank you for putting in all the time and effort to make such an amazing tool!
