True Iron is a plugin designed to faithfully emulate six classic line transformers that have shaped the sound of vintage analog outboard gear. Developed by Shane McFee and Devin Powers, it captures the unique character of renowned models such as the UTC 108 X, Malotki E4M – 4001B, Western Electric 111C, Haufe V178, Marinair LO1166/A, and UTC O-12. These transformers are celebrated for adding weight and depth to audio, making True Iron a powerful tool for enhancing mixes and masters with rich, analog warmth.

The plugin offers extensive control over its emulations, including adjustable strength to fine-tune the nonlinear behavior of the transformers, allowing users to sculpt warmth and dynamic headroom precisely. A wet/dry mix control enables blending the effect subtly or boldly on individual tracks and buses. True Iron also features selectable input impedance settings to maintain consistent loudness or replicate the original hardware's input stage characteristics. Additionally, the Crush controls introduce warm saturation and distortion effects, emulating the sound of transformers driven beyond their limits for added grit and presence.

True Iron is optimized for efficient CPU usage, allowing it to be applied liberally across an entire mix without performance concerns. An enhanced DNA mode offers even more detailed frequency response modeling based on Devin Powers' transformer stereo pairs, providing increased authenticity for those seeking the utmost accuracy. Whether used subtly for gentle coloration or aggressively for transformer saturation, True Iron brings the classic analog transformer sound into modern digital workflows with ease and flexibility.
