I like it. I've never been a fan of the V30 sound but I can't seem to stay away from cabinets using them. I run my main output to the mixer and use the monitor out to my power section/cab. Cabinet simulations are turned off for the monitor output. One (of the many) things I love about the Kemper is the ability to apply EQ to each output separately. I get my rig sounding how I like at my house by using the amp section EQ going direct. Then I tweak my monitor output EQ to closely match what I'm wanting to hear on stage in comparison to the FOH. Works well for what I need.
Another thing I do is to set the master volume control to link with the monitor output. This way I can bump my on stage volume at the cabinet/power amp without affecting what I've set at the board.
