Hi there,
I use my Kemper Amp live and the only problem I have is that when I change rigs with my midi footswitch there is a split second dip in volume. This is a problem with all things digital, Axe FX, line 6 etc. If the Kemper would be the first to solve this problem it would sway a lot of people towards using it in a live setting. The dip in volume is virtually unnoticeable from front house, but for those of us who use in-ears it is very apparent.
