Hello Pinhead and welcome to the crew,
For starters, it's hard not to be buried under lots of rigs which offer different sounds, ideas and original recordings in mind when made. The factory rigs had been my major playground for two years before I tried commercial rigs (mostly taf, some soundside). Later on it was M. Britt and M. Wagener who I welcomed for their way of sond shaping.
Since you probably will have more than one guitar my advice after looking back is: Take one guitar, one rig and be bold with the kpa controls. As Ingolf hinted: This kind of quality time will very much help you to decide if the kpa will stay. By the way: If you've got some good backing tracks, as I'm sure you will, try to blend them in. Your guitar will instantly sound better being in it's natural habitat. There's quite a lot of rigs that seem to be dull or not convincing when played on their own.
That should keep you busy for some time. Mind you: Your ears will hear differently at different times. Always give it a second and a third try before you discard a rig. Next thing: Take it to rehearsal and enjoy the sound, the convenience, the flexibility and the open mouths of your band mates.
