Hello-
I'm a new Kemper user, coming over from BOSS GT-1000, Headrush, Fractal, Helix and Hotone Ampero. I got sick of tweaking settings forever and still having issues and tones that didn't sound realistic.
On a whim, I gave the Kemper Player a try and was instantly hooked. I play mostly in church and rotate between acoustic, electric and bass. Some of the music is from The Torwalts, Upperroom, Hillsong, David Ruis, etc.... We do hour-long sets each week. I can use the Kemper Player as my only unit for all "gigs" going straight to front of house. Editing on my iPhone is perfect. I have each bank set for a different guitar, going from left to right clean all the way to lead. So for example, purple is bass and going from left to right, left is dry, next over is a little reverb, middle is ambient, etc....
The Kemper sounds incredibly good and doesn't require tweaking for hours - even with the stock profiles. All rig changes are totally gapless and glitch-free. Love it.
