Hmmm, that sucks Mark. I didn’t think the Paul’s Guitar was that hot but have never tried one. I have a 513 (which has a hot HB setting that is probably as hot as anything PRS do), a DGR (very vintage, P22 (custom 22 with Piezo with protypes of the 85/15 - mine a 85/14 ?) and a HBii with 57/08. I also have a couple of guitars with EMG. With all of them I set clean sense around -5 and they all seem to work fine.
Try turning off the Stack section completely to eliminate the profile when troubleshooting. Then move the clean sense through its entire range. You should hear what it does more clearly and hear how big a cut/boost it makes. If it isn’t clipping before you add the stack back in then the issue must be with the profiles. Even if it is clipping slightly without the stack engaged the Kemper clips quite softly so a little clipping shouldn’t be a major issue once a profile is added to the signal .
As for MBritt profiles. While they are great (definitely among my favourites) Michael doesn’t really go for totally clean. He likes a bit of hair. If this present in the profile it might be that even turning the gain to 0 doesn’t fully remove the grit.
Thanks for the advice, I will try these ideas and feed back the results.
Played a gig last night using the Tele and it felt real good to get some true sparkly cleans. I love the PRS to play but it just doesn’t get on with the Kemper. I am also going to try dropping the PRS pickups a bit to reduce the output.
