I always finding it interesting to see what people are using, but I personally can't say I really would care in the slightest if anyone I like starts using an Axe-Fx. I've suggested it to friends of course based on great sound, ease of setup/tear down, ease of recording late night etc, but just can't see how, lets say one of my hero's, David Gilmour or Slash, using an Axe would really make my unit any better, or me play any better etc.
Its no different than if such and such guitar starts using the same style of guitar as I have, or driving the same car, or using the same brand of deodorant. Don't get me wrong, probably be a fun conversation to learn that Slash and I both use Degree for Men and have the same favorite shows, foods etc, but if we don't, does it really change anything ?
If someone uses a Marshall and I prefer a Fender for my own music, does it change my enjoyment of their music even though its different than mine ? If they switch to a Fender does that someone make me seem like a smarter consumer or better musician ?
For me, doesn't really matter if my top 10 guitarist ALL switch to Axe-Fx or if none of them are using it, because they are doing what works for them, and I'm doing what works for me. For my needs and sounds, its been fantastic.
