Unfortunately this isn't so. But it's not about the sound.
An analog amp's clean channel stays at its settings, no matter how much I switch presets calling that very channel up.
You really want to force me into another global blocks discussion round, don't you?
I believe that Kemper has this feature, but I don't use it as I no longer "THINK" about my digital amp as a recreation of my old tube amp having "channels". It is an interesting line of discussion though. For those coming from an amp rig (anyone that hasn't been using a digital amp for a long time ..... so most everyone in the new market), channel thinking might be quite common.
I get it.
My point was more about how I can bring my 11 lb Kemper in a rack to a gig and have every amp tone I want to use in that gig right at my feet. My load in is 1 trip (3 space roto routed rack, Shoulder strap bag with cables and foot controller, 2 guitars). I get perfect recreation of my tones every gig. I get bluetooth set control via BandHelper so the only time I touch my foot controller is within a song (and looks like Stadium has a solution for this as well!).
I could never go back to a tube amp rig now. It just doesn't make any sense at all to me.
I wouldn't say that. A small portion of nerds give accuracy a lot of importance, but my perception is that the average user cares more about the unit being able to sound great, then about usability.
My perception as well. Also my anecdotal observations of the people I know that use digital amp devices.
There have been a LOT of complaints for many years about how digital doesn't "feel" the same. That's an accuracy issue and it's because there is a LOT more to accuracy than frequency response. I think some of the problem is with power amps and FRFR units, but far from all, and thats an area where we are seeing significant gains in the latest gen technology.
So, yes, accuracy does matter and more than "nerds" have noticed and care.
Is it an accuracy issue though? My thought is that it is more about the amp-in-the-room experience vs a mic'ed version of the guitar tone (your suggestion about the power amps and FRFR units).
Still, most people will never sit in a room and A/B a digital amp capture or modeler to the real amp. Only a very very tiny percentage will.
I do believe for those that DO compare with their own ears, the amp-in-the-room difference is the most pronounced (vs the FOH sound after micing the cab).
Honestly, my experience (not to be taken as universal truth) is that most people I've talked to about modelers in real life tell me "this modeler sounds awesome", not "this modeler is incredibly accurate".
Only in guitar forums (where the average user is a gear nerd) I've seen "The neverending holy quest for accuracy".
That's why I think accuracy is way more niche than good sound or user experience.
Not that accuracy should be ignored, but I wouldn't make it the main focus of any device, if it wants to sell. Good amp sounds, good effects library, great UI, cool features... Those look like bigger selling points, imho.
I agree with this exactly.
When you go to GC and see someone auditioning a Helix or other digital amp, they are wearing headphones
