Unless I really lower the bridge pu and then raise the low e pole about an 1/8" (or so) above the cover my palm muting sounds bad. But having it set like that weakens the other strings. I guess I'll try some more adjustments tomorrow.
Doesn't help when I play something like my DW CE 24 and then switch to the Paul's. I guess it's possible that I just prefer high output pu's and I have most of my Kemper rigs set with them in mind.
I've always had to adjust any amp for various guitars and pickups, as the different types of pickup seem to push the front end of amps not only differently in terms of gain, but push the frequency balance of the distortion differently as well (for example, a typical humbucker will push the lower mids more, taking the amp in one direction, and a narrowfield pickup seems to push the amp more in the 1 kHz range, creating a different type of distortion).
Admittedly I'm very picky, especially when recording, so I'm going to tweak the amp to fit in the mix the way I want anyway and don't consider it an inconvenience to twist knobs. I can see where it might be more of a PITA with a Kemper, having to modify the presets one creates for each model. Still, it might be worth trying before you unload the guitar.
Obviously, we all feel differently about various types of gain. When business forces me to record something in mid to high gain, I generally use my CU24 PS, which is a pretty bright guitar, so I must like a brighter distortion tone, but then I'm usually trying to cut through a mix with my guitar part, and brightness gives the track a bit more cut relative to the bass, drums, etc.
You've probably already tried using a real or virtual boost pedal. I sometimes do that when trying to get a higher gain sound. I have two boosts on my pedalboard, one by Suhr that can be switched into becoming a sweepable/parametric midrange boost so particular frequencies can be emphasized, and another by Pettyjohn with low and high frequency boost/cut EQ that sounds great and can help shape a signal the way I want. Of course, a dedicated EQ can do pretty much the same thing, and yeah, I use one of those to shape my tone with various amps from time to time as well.
You probably know all this stuff and don't need to go over it again, but I post this in case you haven't already thought of it.
Heck, when I'm recording, even which mic preamp I use can make a difference, let alone which mic! I even have cables for certain sounds I want to get. I think I might be in need of psychiatric help - I go overboard with this stuff.
