Yeah….but that’s just it. Kemper says that there isn’t a difference (as far as I remember) between the OG toasters and the later models. I can just say, that the difference from my OG toaster to the Player is massive. I always hated the sound of palm muting on high gain, because there was some “digital fizziness” I couldn’t get rid off no matter what profile or IR, I used. Now it’s not there on any right now at all. I was literally blown away from the very beginning of plugging in the Player. It’s amazing. I’m looking forward to 2.0, but I already have something really great, so I can wait.
There isn't a tonal difference, but one thing is different: the input section of the Kemper Head in Browse Mode is usually locked, so you can keep it through all rigs. The player does not lock the input section, so the input settings are coming from the rigs itself.
I'd assume that you need to adjust your input section or try turning "input section lock" off and check out the rigs again, if you have still issues with palm muting.
