I don't use the fx on the Kemper.
I'm a record producer, and in most situations there simply isn't time to go through the menu's and pages.
I do have a comp and wah set up on every amp, but for the most part, I'd put the fx on during the mix anyway.
An editor would be great!
It would mean that the kemper doesn't have to take up space in the already cluttered listening position that I spend most of my time in.
It would also allow for faster settingup of tones that may help the talent feel more inspired.
There seems to be more and more cool things being added to the kemper that I just don't have the time to make use of.
Too many button pushes to get to the desired parameter.
