So @[Nathan] kindly reamped some DI's through his JVM and sent settings. All pretty typical stuff, OD1 Orange:

My first AxeFX tone was eyeballing settings, trying to be as generous as I can to match the tone. If you put settings like this in, it sounds bloated and farty and not like how you'd expect a JVM.

Just to prove the tonal difference is beyond pot tolerances and tapers, the next tone sets the presence and treble to both to 10. This ends up sounding a lot closer to the JVM at "typical" settings.

Lastly, I did a tone that I just dialled totally by ear. This involved being more heavy handed with the amp EQ, changing the preamp LPF, changing the MV bright cap etc. It's not exact, but it's possible to get in the ballpark. But to get it to sound like a "typical" JVM, you need to get your hands dirty, AND use more extreme settings. I don't really associate the JVM as the kind of amp that needs weird settings or a lot of work to sound good, most people seem to use roughly the same kinds of settings.

Tweaking by ear (TOTALLY different mids, treble, presence settings as well as other deeper tweaks):

I've always felt the JVM models didn't really represent my experiences with the amps, particularly for sounding too dark/muffled. I can get close enough to be happy with some tweaks, but this only really works when having the real amp to reference against. I'd WAY prefer to be able to just dial the amp like the real thing and get typical tones with more ease.
The real JVM is an amp I think of as fairly bright/tight/twangy/aggressive. The Fractal model leans more fat/fuzzzy/dark/bloated unless you massage it into something else. It doesn't really remind me of a JVM unless you do those sort of adjustments.
