I just wanted to say that I really think that there hasn't been enough talk around these parts about using the equalisers in the Kemper to really sculpt your tone.
Honestly, a post-amp EQ can really transform a tone that you thought was good but not great. Think of it sort of like the EQ on a Mesa Mark series amp or a VHT/Fryette Pitbull.
The EQ lets you sculpt the sound to suit your guitar as well. Just put it after the input section to tailor what you're feeding the amp.
And post EQ, it has a radical effect that can make your tone stand out.
I'd recommend not going overboard (though you can do that as well), in my experience, start with a base tone and then put an EQ in the X slot.
Because the EQs have more frequencies to alter than the controls on the face of the Kemper, it allows you to fine tune your sound in a way that the controls on front or in the output section could ever do.
You could even use one to set up your Kemper for use in a variety of environments. Just create the EQ and then save it as a preset.
I just did a clip demonstrating how an EQ pedal in the loop of a real amp can completely alter it. Have a listen. First part of the clip is the raw amp tone, the second part is with the EQ pedal on. The EQ is in the loop, similar to how it would be after the amp section of the Kemper. Just a single tracked guitar.
I used to like the tones I was getting earlier, but I am completely blown away with how good they sound with the EQ on. Can't wait to do some profiling with one.
Try it out. You'll be amazed.
