Exactly. Not listening to what is said. THIS HAS BEEN DONE. Why do you ignore that?
This has been done on consumer audio electronics devices that play back pre-recorded music. Meant for home use in a room of an approximate same size. That absolutely matters compared to live audio.

This whole thing can be easily solved. Anyone simply needs to plug their Axe into a device that has this loudness button and press it. Does it work? Does it not work? Chances are it will not work the same way as pre-recorded music in a room in a house.

Ok. Explain to me why known differences in human perception based on frequency and sound level which have been accounted for in circuitry are impossible in the Fractal world. I’m listening.
I can't. Because I know where my expertise lies, and where it doesn't. And my expertise doesn't lie in electronic design.

Something tells me that yours doesn't either. Yet, you seem to put your insight on par with someone who clearly knows thousands of times more on the topic of electronic design than you do.

The "Loudness" controls in old Hi-Fi gear was nothing more than a bass/treble boost. It's a gimmick. It was supposed to compensate for the reduced sensitivity of human hearing at lower volumes. It's not accurate, never was and can never be. There are a myriad of reasons why, the most glaring is that you have no way of knowing what the SPL is (without a meter). Since equal loudness contours are dependent on SPL you can't compensate if you don't know the SPL.

The Axe-Fx has no idea of the sensitivity of the amplifier and speakers connected. Therefore it can't possibly know what the SPL is and concomitantly can't know how to compensate.

Here's an article on what's wrong with "Loudness" controls:

I give up. You guys can be content with whatever. My notion that FAS can offer an adjustable loudness curve like some hardware I owned is misplaced. Whatever.

Thanks for proving my point.

Maybe stating the obvious, but anyone interested in loudness curves can easily import one into the Axe as an IR, yes ? Not continuously variable, but with a little experimenting probably not hard to find something useful for quiet home use...
