True Iron – the true sound of transformers

Kazrog - True Iron 1.2Add warmth and heft to your tracks and masters.

True Iron is a plugin made by Shane McFee 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.

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.


True Iron is great for adding mojo, life and heat to cold digital tracks.”

Armando Avila – Multiple Grammy Award winning producer/writer/performer

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 LegendTrue 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)

“These guys modeled some classic iron and I like what I’m hearing! Just running through it adds some bounce. The ability to dial in the saturation is a blast. You’re going to want to turn this baby up!”

Phil Moore – Retro Instruments

John Paterno“True Iron is deceptively simple but infinitely useful!”

John Paterno – Producer/engineer (Lustra, Soraya, Robben Ford, Eros Ramazzotti, Bonnie Raitt, Badly Drawn Boy)

“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 – Producer/engineer (Dierks Bentley, Kelsea Ballerini, Lady Antebellum, Backstreet Boys, Keith Urban, Ingrid Michaelson, Little Big Town)

True Iron accurately reproduces the sound of high quality vintage and modern transformers, adding the pleasant saturation of an overdriven transformer core, the beefy pleasing euphoria of true analog sound. True Iron enhances overall sonar cohesiveness on whatever it is put across adding solidity and focus to mids and bottoms, making bass and kick more rhythmically defined within a mix.

Used on the mix bus, True Iron helps take the edge off of digital recording while maintaining the sheen on each side of the mix and providing the ‘glue’ that only high quality transformers offer, and the wet/dry mix feature brings in parallel performance while maintaining clear detail throughout the mix.”

Rick St Pierre – CEO, Wizard Amplification Inc. & The Room Recording.
AC/DC (27 year studio and road amp tech), Aerosmith, ZZ Top, Jimmy Page, Lynyrd Skynyrd, Bachman Turner Overdrive.

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)

True Iron lets you add analogue warmth and weight to your digital tracks and mixes, or for real fun try the full crush mode and experience the exuberance of analogue console distortion. The plugin design is elegant and the controls are very intuitive. A must-have for anyone mixing inside the box. Well done, Shane and Devin!”

Bruce Sugar – Grammy nominated producer/engineer (Ringo Starr, Joe Walsh, Ozzy Osbourne, Robert Downey Jr, Michelle Shocked)

“Wow! True Iron is amazing! It sounds and reacts exactly like hardware transformers. It’s an absolutely essential tool for me now. Finally! The sound, and ‘feel’ of outboard Transformer saturation in my DAW! Love it. “

Jack Trammell – Film Trailer Composer, Mix/Mastering Engineer (Mission: Impossible, Doctor Strange, Westworld)

“Kazrog True Iron (plus something like Sonimus Satson) is an absolute no brainer if you want your music to actually sound like a record. If you think you can get this sound staying up all night with your tongue hanging out of your mouth and one eye open vehemently tweaking and tweaking and tweaking your stock DAW plugins, you’re high on bathsalts!”

  • 6 transformer emulations in one plugin – Models are based on the UTC 108 XMalotki E4M – 4001BWestern Electric 111C, the Haufe V178, Marinair LO1166/A, and UTC O-12.
  • 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.
  • DNA mode (new in 1.2) – This is an enhanced level of frequency response modeling based on Devin Powers’ individual transformer stereo pairs. This mode will incur additional CPU usage, but is even more accurate with the original hardware being emulated. Disabling it reverts back to the simplified,
    ultra-efficient yet still highly accurate modeling used in True Iron 1.1.5 and earlier.
  • 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.
