Neural DSP Tone King Imperial MKII does not have a permanent "free link" for a full version, but you can access a legitimate 14-day free trial through the official Neural DSP website How to Get the Free Trial

Unfortunately, I couldn't find any information about a "free link" for the Neural DSP Tone King Imperial MKII plugin. It's likely that the plugin is available for purchase or subscription through the Neural DSP website or other online retailers.

: Users often share custom preset packs for the Tone King MKII. For instance, this forum thread on the Neural DSP community site includes links to free clean and crunch presets.

Built-in for cranked tones at any volume.
