Having A LOT of fun. I hook up the Kemper and Axe Fx II to a Radial AB switch box, so that both are receiving signal to the respective units. Then I have another AB switchbox that I use to switch XLR outputs to an Atomic FR. I'm REALLY impressed with the KPA. It sounds and feels like I'm playing through a tube amp, not a model of a tube amp, not a physical model of a tube amp, but a tube amp. Of course, not all profiles are equal and like the amps themselves, some I like, some I don't, some I love. I'm not going to offer any disrespect to the Axe because both units sound great, do somethings better than the other, but at the end of the day, all I care about is how it sounds. I like to tweak the sound, but don't have OCD when it comes to my sounds. I also don't have need for crazy effects routing - pretty straight forward mod fx, OD, delay and reverb. I actually use an M13 because I prefer the ease of use and sound over the Axe's fx (I'm probably the only one who does) The KPA sounds great and is easy to use. It has the ease of use and simplicity of a POD with the sound that Line6 has been claiming the POD has for ten years.
I'm not going to load new firmware, make my own profiles or load others until I feel comfortable navigating the unit. I dont want to toast the unit since shipping back to Germany will be a pain. In some ways the KPA is very intuitive, in other ways, I have to refer to the manual.
Look forward to contributing my own profiles at a later date, but appreciate everyone sharing their profiles.
