Display MoreBy presence switch do you mean the knob?
If anything, IMHO, cranking the bass and / or cutting the mid knob would probably be the worst things you could do in most recording situations.
If you want to keep your options open so that even your engineer can't complain, just record simultaneous-DI tracks from the KPA's Direct output every time you track. That way if the tone you chose on the day doesn't end up suiting things perfectly, you or the engineer can reamp to your heart's content until you find something that does.
Switching Rigs in real time whilst the mix is playing theoretically puts you in the best-possible position to make such judgements 'cause you're listening and not playing.
HTH
Yes the presence knob. When I backed off it today it was a game-changer. I never touched it in the past, because I thought it would change the original profile, but it seems like they have nothing to do with the profile it's just the default settings of the Kemper? Roger that on the DI. I will have to do that.
