My tone library for the NUX MG-400 includes 168 presets, available into 4 packs, or as a 4 packs bundle : Cleans & Acoustic Simulation, Edge & Crunch, Drive and High Gain. These cleans/crunch/rock & heavy rock/metal tones uses all the guitar amp models. The focus here is on getting the best base tone with each amp model, in presets which you can then personalize. There are also a few song-specific presets. All presets use custom IRs, which are embedded. These presets are for FRFR setups/studio monitors/straight to a mixing desk, and are optimized for stereo, while being mono compatible.
The High Gain pack has 46 presets with the following amp models, for either heavy rhythm or leads : SLO 100, Fireman HBE, Die VH4, Dual Rect, Brit 2000, Uber Higain.
All the high gain tones from this video are from this pack :
