True Iron – the true sound of transformers

Add warmth and heft to your tracks and masters.

True Iron is a new plugin made by Shane McFee in conjunction with Devin Powers (Powers Music Company). It accurately emulates two classic line transformers, known for their use in many of the biggest names in vintage analog outboard sound processing. In USA mode, True Iron emulates the UTC 108 X, and in Euro mode, the Malotki 4001B.

  • Bonus: Take a look behind the scenes at some of the transformers that inspired the plugin.

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.


  • Two transformer emulations in one plugin – USA and Euro modes emulate classic transformers used on hit records of the last several decades.
  • Strength – Adjust the tendency toward nonlinearity of the transformer, continuously variable to allow boosts and cuts in warmth while maintaining the large headroom classic transformers are known for, throughout the range of the control.
  • Wet/Dry Mix control – Blend just as much True Iron as you want into each track and bus in your mix, to taste.
  • CPU Friendly – Run an instance of True Iron on every track and bus to elevate your mix without noticeably taxing your CPU.
  • Selectable input impedance – Unity (default) for convenient dropping into existing projects without apparent loudness changes, and boost for the most accurate emulation of the input stage of the modeled hardware.
  • Crush and Crush 2x – Add warm overdrive or distortion to your tracks, emulating the sound of transformers pushed beyond their intended operating range with up to +48dB of auto compensated gain.

Ross Hogarth“I’ve been way into having real iron transformers on my mixes and recordings for a good portion of my career. The True Iron plugin is a game changer – having this indispensable sound on recall in the convenience of a DAW. This is a plugin that just makes everything sound better! With the ability to add extra harmonic distortion on the fly, and blend wet and dry signal to taste, it opens up even more possibilities on the fly that would be tedious or impractical to do with hardware.”

Max Legend“True Iron gives you a solid, clean low-mid range without touching a button.”

Max Legend – TV and Trailer composer (Trailer campaigns – Avengers: Infinity War, Spiderman:Homecoming, Kong:Skull Island, Resident Evil:Final Chapter)

“Right away, True Iron did something really nice to my mix in the low end and the mid range definition.”

Danny Lux, SESAC Award Winning, Emmy Nominated TV and Film composer

True Iron has a solid transformer sound. Loving what it does to the low end! Sounds like the real deal and not an effect. This will be a go-to tool in my plugin arsenal.”

Pete Lyman, Mastering Engineer, Infrasonic Sound (Chris Stapleton, Tom Waits, Zac Brown Band)

“Crazy and over the top is easy to find in plugins nowadays. What’s nearly impossible is complex, subtle distortion and harmonics that enhance the sound without destroying the character. Until now. True Iron is the first time I’ve heard this magic. It’s so incredibly useful – it will change the way you work.”

F. Reid Shippen (Dierks Bentley, Kelsea Ballerini, Lady Antebellum, Backstreet Boys, Keith Urban, Ingrid Michaelson, Little Big Town)

True Iron is perfect for gluing the low frequencies of kick drums and bass guitars together in such a way they compliment each other effortlessly.”

Jason Suecof, Audiohammer Studios (Deicide, Carnifex, Death Angel)
