This is cool, it's a little bit "batteries not included" so you need to get some Models for the amp part: https://github.com/pelennor2170/NAM_models and some Impulse Responses (IR files) for the cabinet emulation.

When you put them together you can get some good results, maybe a little bit noisy.

The important part is trying to develop a library of models for plugins to share and when paired with libraries of impulse responses and other FX you can build up common guitar tones. It's not especially user friendly, which is what you pay for with other commercial plugins

That's very exciting. Some day a a mere mortal might be able to play a facsimile of a dozen slightly-different hand-made Dumbles.

One thing that this approach (and profiling) might not be able to do is what Ben Adrian's sound design team in Line 6 did, where they've come up with some delightful "amps" in the Helix that don't have real-world equivalents. For example, my favorite, the Ventoux, which he describes like this:

"The idea was to create a “coveted boutique amp” that had a different origin story. Most coveted boutique amps come from modified black panel fenders or modified marshall circuits. I wanted to do the same thing, but base it on the early 70s Orange circuits and the mid-wattage Fender Tweed circuits."

I'm not sure how one would to that with a NN approach.

Edit: now I'm wondering if one could make a large model trained by all the amplifiers, and have it dream up amps that don't exist.

Fractal's AxeFx has been able to do that for a long time. It has a couple different Dumbles and you can tweak the modeled circuitry in a myriad of ways because it is not a profiler, but rather it models the audio impact of each component that makes up the amp.
