Axe-Fx' tonestack does not mimik the original amps' behaviour? :o

What was all the fuss about the Profiler's tonestack then?
Wow, I did not know that...

Them having problems replicating the Boogie makes sense but the Fender too?

... visualising the KPA with a set of robotic arms that operate knobs and switches on the amp during profiling

Nothing is perfect.

This should not be necessary. I don't think there are more than a handful of different tonestacks around... With just a tonestack library we should be done.
But the point is, unless I missed a lot, that the Axe was supposed to clone every amp at circuitry level
@ Inglof: LOL
-
Beyond "nothing is perfect" - neither are the original amps. Their tonestacks have fixed values, too.
AND: I didn't turn tonestack knobs when I *WAS* using my Marshall or my Fender. I would set it, forget it, and that's it

I think he means the center frequencies are fixed on most amps

Got it
About not tweaking real amps... I'm not sure

"About not tweaking real amps... I'm not sure"
The knobs on my Marshall are set for my favorite sound. The knobs can't be tweaked for different sounds at a gig, so I've always used multi effects pedals and/or rack units to get other sounds from it. Doing it that way, I could save the tweaks, and recall them as needed.
Or, I could just pick up a different guitar to change the sound of the amp

The 'point to point modeling' or whatever Cliff calls it - where he uses the schematic to create the amp model isn't very accurate. How do I know? If you've played a real Bogner Uberschall, the presence control is more like a midrange control - it's not like a typical presence control at all. The Axe model of a Uber doesn't mimic it's controls as far as the presence control goes. So... it's not really modelling the component values. Not saying it sounds bad, but it's not as accurate as they lead you to believe.

As I understand it, it's much less of a "this is a model of an Uberschall" and more a case of:We've got these digital recreations of tubes, capacitors, resistors, filter circuits, etc.. etc... lets look at the schematic for the amp we want to make a model of, and lay them out in that order - like lego... then dial in the specifics to match. It's *fairly* accurate, but with strange little quirks that some amps have, it's not going to capture it 100%
But then again, nor does the Kemper! It's all about what workflow works best for you. Good time to be a guitarist!

Ah, ok
I see/do it the other way round, I sometimes need a different guitar and hence tweak the amp
@ Okstrat: this is exactly the point of the thread. All that talking about the Profiler's flaws... LOL

Totally. I remember Fractal folk being up in arms about how the Kemper tone stacks didn't work like the real amps and when I brought up the Uber it wasn't a big deal but on the Kemper it was to them. Was pretty funny. And yeah, it is a great time to be a guitarist!
