Definitely understandable why they’d want to be cautious with it, but demonstrating absolutely ripping tones should be pretty easy for them to do. They have access to some of the best guitarists ever to have lived, a decent studio, the most ideal conditions imaginable.
I think it’s just a case of them planning the right approach - picking the right examples and framing them in the most appropriate contexts. I don’t think they need to be TOO cautious about it, I think a bit of bravery and confidence goes a hell of a long way.
The opposite is something like what Nembrini do, a half assed soundcloud playlist of largely dreadful demos. I’m not surprised at the response of them posting AxeFX preset demos - something that has been dialled in by someone else is never going to sound quite right when played by someone else. Demos should show the absolute best of what’s possible, not just “here’s me playing a random ass preset that I didn’t even make, and not sure I even like”.
I think if I made a playlist playing through stock presets on any device they’d sound underwhelming. It would be like trying to mix a song using only presets made by someone else
