Pretty sure that an editor wouldn't convince me to move to the Axe FX or Helix. Seriously, fuck that school of thought.
If the "market evidence" suggests that there are hordes of people selling the Kemper due to the lack of an editor, I'm sure the company will look into it more seriously than if some users state on a forum that they will look for another device if the company does not give them what they want.
No one is denying that an editor would be good. But the way the issue is being played up in this thread is ridiculous.
It'll come when it comes, if it comes, and if it doesn't too bad (aka sell your Kemper).
