Manufacturer's ID: Ironman II - Attenuator

What we say:

At A Glance:

The Tone King Ironman II Mini Attenuator is great for those looking to get that cranked amp sound at a lower volume. With proprietary reactive load and transformer-coupled technology the Ironman II effectively reacts to your amp signal much like a speaker would, creating a wonderful sounding attenuation that doesn't lose out on life or responsiveness as you lower your volume. This Ironman II is designed for 100 Watt amps or less.

Features We Love:

Reactive Attenuation

Attenuation is a tricky game, if it's not done right, it can leave your amp sounding lifeless after you bring the volume down. With Tone King's proprietary technology it reacts to the amp signal just like a speaker, with a much needed ebb and flow. The result is a natural sounding attenuation that still allows your amp to breath even as you lower the volume.

Solo Mode

This feature is perfect for setting variable volume levels. With the Solo mode you can switch from your Hi/Lo attenuation levels up to solo. So you can set your levels and then engage solo for a boost whenever you need it.

3 Position Presence control

This control allows you to tweak the high end of your sound to perfectly match your environment. Providing a cut of 0dB, -3dB, or -6dB this control tailors the brightness and compression of your sound so you can find your perfect sound.

Impedance Matching

A very unique feature of the Ironman II is that it can match the impedance of two different devices. With an input for your amp, and an input for your cabinet, it can turn mismatched amps and cabs in to perfect partners.


  • Natural sounding attenuation
  • Sturdy Design
  • Presence control
  • Simple clear layout


Solo Mode
The Ironman II provides a unique Solo mode which can be engaged using the included foot switch. The Solo function selects between the Solo and Lo/Hi range setting of the attenuator allowing you to toggle between with 2 different volume levels. This is useful for giving the guitar that extra volume kick needed for a guitar solo that cuts through the mix or two rhythm level settings.

Impedance Matching
One unique feature of the Ironman II is its two Impedance controls - one for the amplifier input, and one for the speaker output. These dual impedance controls allow you to match your speaker to your amplifier, even if the speaker impedance differs from the amplifiers' output impedance.

Use as a Dummy Load
The Ironman II may be used as a dummy load, to provide a proper load for your amplifier, with no speakers attached. This is typically done in recording, where the Ironman II's Line-Out will be used to drive a mixing board, or when an amplifier is being "slaved" to a larger amp (with the Line-Out signal driving another amplifier).

Presence Switch
The Presence switch provides subtle control of brightness and compression. It allows you to tailor the response to match your acoustic environment, and to correct for an overly bright amplifier. Three settings are provided: 0db (brightest setting), -3db, and -6db (darkest setting).

Attenuate / Bypass Switch
The “Bypass” mode, which is in fact not called ‘bypass’ is the far right setting of the attenuation knob (0dB) in the Solo mode. In Attenuate mode, the attenuator is active, and in Bypass mode, the attenuator is disabled. In Bypass mode, the speaker outputs are connected directly to the amplifier input, and the attenuator circuitry is completely disconnected from the signal path.

Line Out
The Ironman's Line-Out jack provides a line-level signal that can be used to drive another amplifier, mixing board, computer sound input or any other line level input.

Customer reviews

Overall Rating 5/5 (2 reviews)

This is a pricey but really effective attenuator. If you have a decent wattage amp and want to keep the tubes warm enough to get the perfect sound at a sensible volume you need this. Well worth the price tag.

Does exactly what it’s supposed to. The best.
