I’d love to experience this, but so far it still seems like the technology is more in the “good enough for most people/situations” rather than indistinguishable.
If I played metal, or was backing a pop group, one pedal di'd to the desk sounds like the dream
I don't play live so for me it isn't an issue, I just have set of monitor speakers to play on.
>amp induced sustain
As in Feedback? This too is applicable primarily for live setting, but I don't know how well it'd work as I haven't tried it.
I think my favorite thing about it is that it just allows me to play more. I run my computer output through the rig, so everything comes out my headphones. This means I can play rock as "loud" as I want, with any song on the planet, and the whole house can be sleeping. Very much worth the trade offs for someone who just wants to play and not geek out about gear.
On a modeling amp, I have not heard one that doesn’t introduce extra digital artifacts into the tone. It’s like the difference between GCI and IRL.
Another is on the other end of the amplitude spectrum, very quiet playing, where I hear extra digital artifacts introduced.
As the other poster mentioned though, these differences may not come across at all in a metal/pop setting.
But there are always exceptions. As someone that worked as a recording engineer for 7 years, and spent time intentionally training my ears with blind tests, I can tell you that there is a definite aural difference between a real tube guitar amp and a modeling amp. Other recording engineers I assisted could hear it too.
