I agree with the spirit of this, but I feel like a decent number of us using Fractal devices may not understand amp circuitry enough to know how to take Amp A to Amp Z.
The tools are there, sure, but if you don't have the right knowledge set to use them then it may not be as "infinite" as it is for some.
I know this is all learnable, but it's such a big topic it's hard to know where to start sometimes. It also seems like a lot of learning to just, say, make a Benson Chimera from some sort of Fender.
You honestly don't need to know what bias excursion means etc. There is so much you can do with nothing more than the basic EQ controls and picking the right cab sim.
I've been able to match amps that don't exist by using Fractal models without ever doing any deep dives into the advanced params. As an example, a Bogner Goldfinger 45 SL is a cool amp that can cover Fender Super Reverb cleans, Marshall Plexi, JCM800 and Bogner Shiva tones. But guess what, you already have all those sounds built in your Fractal so you don't need a Bogner Goldfiinger model on it. How did I figure this out? I had the real amp and simply compared, turned knobs and listened.
My process for trying this sort of thing is to think of "what is the closest amp model to this amp". You can pretty much split nearly all the amp models to Fender, Vox and Marshall categories. If it's a cleanish amp, you can pretty much bet it's based on a Fender or Vox. If it's a rock beast, it's probably a modded Marshall of some sort.
From there you then can look at e.g specs of the amp you are interested in replicating. Ok, it has EL84s, so it might be a Vox-based one. EL34s? Maybe Marshall-based. Oh, the cleans are very similar to Fender blackface type amps, let's go through those. Knowing your basic "flavors" goes a long way.
But people want more preset versions of their favorite, rare or expensive amps. This satisfies their collector mindset and gives them the comfort that they can pick amp X and it will sound like it. This also helps them avoid ever having to listen for themselves or spend the time to figure out how to make the most out of the 300 amp models already in there.
