I bought my first one in 2012, working as a backline tech, so as to not having to find and lug around a bunch of backup amps on tour. The first year and a half people kept asking me what I was doing when I profiled the amps in production rehearsals, then they caught on. And now I have four Kempers in my arsenal. I personally don't like playing through it but it's a good tool and I think it's still ahead of the competition. Yes, there are "better" profilers and better playing feel but the Kemper still wins out on the average score for me, in terms of work flow, switching lag, effects, the different form factors, the ability to work with the hardware only. And the generosity and work ethic of Kemper team!
I'm still on tube amps though![]()
