For the record, this doesn't happen often. Usually I can emulate captures fairly well with good modelling units. Brown packs have been an exception.
But just another experience with tonex: spent quite a bit of time again dialing in a VH4 (online through my friend who has one lol). He finally shot the capture with my desired settings. Amp only.
Sounds and feels amazing. That, while up to now fractal VH4 silver has been my go-to amp for a lot of heavy tones.
So I compared the capture vs my fractal VH4 preset. Did a lot of tweaking, which usually isn't required. By the end, there was still a considerable difference between the tonex capture and the fractal VH4.
The fractal sounded somehow garbled in the low end. Best I can describe it is like a hairball a cat spit out, comparatively speaking. Input cuts didn't really bridge the gap, neither did all kinds of master vol settings, advanced settings. EQ matching brought them closer, but the tonex capture still felt much better to play through.
I'm not saying the fractal sounds bad. The above comments are in comparison to the tonex capture. But so far, the tonex VH4 is my favorite diezel tone. It's replacing a fractal tone I was very confident about for ages.
The annoying part is I can't quite replicate this on the fractal lel. So that's an example where tonex one takes the lead. Maybe I have more success with fresh ears, today, because I'd like this tone on the fractal as well.
Fractal has said their next gen products will support NAM. I think you can emulate most tones very well with such modelling, but then there's cases like this, where nothing seems to bridge the gap.
I continue to be impressed by tonex one. And that's from someone who shot a million Kemper captures, ending up just using modelling for years, because it just sounded better, felt better, and was much more convenient.
