Aethis

Did not convince me much, so I deleted the plugin soon again.

Noctis does not sound better to me than a cheap, tubeless Metal-distortion pedal, very thin, scratchy and unbalanced sounds, but no typical, well usable, all-tube high-gain Metal sounds for me, if I compare them with the ones, I get out of a Rectifier, SLO 100, 5150, VH-4, Savage 120, JVM, ... real amp or good amp plugin.

Ember simply sounds boring and meaningless to me, not like a Fender, nor like a Marshall, not like a Vox or Orange, nor like any other good tube amp, I know, I do not hear and recognizable character and uniqueness at all and Lumina does not sound bad, nicely warm, but without any convincing treble bite and dynamical reaction to attack also is poor, you do not even get any edge of breakup sounds out, but for clean sounds I anyway prefer just using guitar and audio interface and maybe an eq plugin.

For all three amp models I already have better sounding Tonex models of my real gear, but also better sounding plugins from competitors.

The harmonizer is a nice idea, but I have not even tried it, as I disliked the amp sounds too much and all other effects anyway are not really my taste, only average, no tape echo or spring reverb. Two undefined IR's only and no option, to deactivate it and use external ones instead or a built-in IR loader also does not impress me much.

I maybe used the harmonizer, if it had been offered as separate plugin.

The programmer obviously is a very young guy, so I would say, the talent is there, but at the moment not really the necessary experience, concerning great, if not legendary guitar tube amp sounds.

The market already is overloaded with amp plugins, a lot of them simply sound bad, some usable and a few ones great, so if you are not capable of creating something really outstanding and top-notch sounding, better let it be in my opinion.

The pedals, effects section also only is average, something, I dislike on most contemporary amp plugins. No compressor, drive, delay, reverb pedal in reality sounds the same and every player knows, why he just uses a certain pedal on his pedalboard and not another one, but here you only get exchangeable average effects, which you anyway hardly can use for (re-)creating your own, personal sound, so you anyway will need additional plugins of your own gear, so these sections are completely obsolete for me.

What I also do not understand is, why so many people meanwhile more or less just copy the NeuralDSP plugin look, instead of creating something better and more convincing. I personally never liked it, much less most of their amp plugins. But this is another theme...
