First week with a Kemper. Reverbs not as bad as expected; the straight-forward hall (which is my usual go-to) does the job for me, makes the amps sound nice and open.
Thought less of the mods until I played around with them this morning. Rotary/phaser/chorus all sound pretty good actually; there's a mix dial and they stack well.
I like the feedback suppressor/notch filter idea a lot.
