What is the Metallurgy Collection?

The MetallurgyTM Collection of amplifier and effects plugins was created specifically for guitarists who wish to quickly and easily access contemporary versions of classic and modern metal tones—as well as craft original tones of their own. The Collection bundles the Modern, Thrash, and Doom plugins, which are also available individually.


The Metallurgy Collection plugins feature amplifier and effects models drawn from the award-winning HX® family of products.


How many amp models per plugin?

Each Metallurgy plugin features four amplifier models carefully chosen to deliver a full range of genre-specific tones.


What kind of effects are included?

Pre-amplifier Effects

Each Metallurgy plugin features 3 (or more) mono. style-specific effects, as well as a polyphonic capo, that can be used before the amp in the signal chain.


Post-amplifier Effects

Each Metallurgy plugin features two stereo, style-specific effects that may be used after the amp in the signal chain.


What about Cabinets, Microphones, and IRs?

Each Metallurgy plugin features a choice of eight speaker cabinets and eight microphones, all based on IRs. Two mics may be selected and combined with a stereo room mic array, and up to two third-party Impulse Responses (IRs) may be substituted for the factory mics. Once you’ve logged in and authorized your Metallurgy software, IRs purchased from the Line 6 Marketplace on the same account will be made available in Metallurgy.


Can I automate parameters in the Metallurgy Collection?
Yes. Nearly every parameter in the Metallurgy Collection can be automated.


Does the Metallurgy Collection support MIDI parameter control?
Yes, nearly every parameter in the Metallurgy Collection can be controlled via MIDI CC.


Is amp switching and amp bypassing via MIDI Learn or automation available?

Switching channels via midi/automation is not available because the plugin would have to load the DSP of the alternate channel – which is essentially another model being loaded. Changing amp models in general is not supported via midi and automation.


You can bypass an amp model and its DSP by disabling (bypassing) the amp view in the top toolbar. That also is not supported via midi learn or automation.  There are other ways to bypass/mute that are midi/automation supported within the cab view’s mixer.


Is the UI resizable?
Not at launch. We’re working on it.


Does the Metallurgy Collection support Retina displays (2x resolution)?
Yes. The Metallurgy Collection includes Retina support.


Is there Undo/Redo functionality?
Yes, Undo/Redo is included at launch, along with A/B Compare. 


Does the Metallurgy Collection have a built-in tuner?
Yes, it does include a chromatic tuner.


Will there be a standalone version?

Yes, each plugin includes standalone functionality.


Are there any artist presets?

Not at launch.
