Tone King Ironman II Power Attenuator

The Tone King Ironman II is a 100W precision power attenuator allowing tube amp enthusiasts to achieve rich, natural overdrive at any volume. The Ironman II is crafted with a tuned reactive load circuit and gives transformer-coupled attenuation to preserve your amp’s tone while reducing output. Along with an analog cabinet simulator for recording use, the Tone King Ironman II is a versatile attenuator for any amp.

Reactive Load and Transformer-Coupled Attenuation

The Ironman II’s reactive load impedance curve matches your speaker’s complex impedance, enabling your amp to respond as if connected to a real cabinet. Its transformer-coupled attenuation divides power between your speaker and the reactive load, safeguarding tone at each volume setting. The result is authentic power tube saturation and compression at whisper-quiet levels.

Analog Cabinet Simulation for Recording

An all-analog cabinet simulator provides balanced XLR DI out with speaker emulation for recording or front-of-house use. Select between center or edge microphone placement and ground lift options to match your needs. Compared to digital IRs, the Ironman II’s analog circuit achieves a rich, nuanced speaker tone that brings your amp’s sound to life in the studio or on stage.

Unparalleled Control and Versatility

The Ironman II grants an unparalleled level of control over your tone. Its dual impedance controls enable you to match your amp and speaker impedances, even if mismatched. An effects loop allows the insertion of pedals between the attenuator and speaker. A presence switch provides -3dB and -6dB treble cut options to compensate for an overly bright amp. An included footswitch toggles between two volume levels for lead boosts. Run the Ironman II as a 100-watt dummy load without a speaker for recording direct or driving another amp. A line-out jack feeds mixing boards, audio interfaces, or power amps.

Roadworthy and Built to Last

Housed in a rugged steel chassis with durable powder coating, the Ironman II is built for life on the road. Its components are hand-selected and wired to exacting standards for years of reliable service.
