I have been fighting my KPA for a week now trying to figure out why it suddenly sounds different. I think it has happened before and a flash format and init took care of what ever it was. Now I can't seem to correct it.
Here is an example using the stock profile "Sabbath" with the delay turned off. The delay made it even worse, it was the only effect on this profile. Clean sense 4.0 Dist sense 0, no clipping.

I don't know if that's what people have called phasey, but its nasty sounding. There is a lot of extra noise, swooshing sound, cocked wah kinda like, harshness, popping, and kinda muffled all at the same time. All profiles are doing this, clean ones are less noticeable, but they are affected. Here is what I have tried.
It started on 1.5.2, so I upgraded to 1.5.3.
Downgraded back to 1.5.2
Reset global settings
Flash format and init
Downgraded to 1.1.1
Reset global settings
Flash format and init
Upgraded back to 1.5.3
Changed all my cables
Disconnected Midi and extra cables so it's just input and left main out to my interface.
Tried five different guitars. Single coils, humbuckers, actives.
Tried different headphones. Currently using ATH-M50s which have always served me well.
This was recorded through my POD HD 500's FX Return. Today I turned off the stack and recorded a clean signal that passed through the chain and then reamped it using VSTs and IRs and it sounded great so I ruled out the HD 500 coloring it. I also recorded it through my Focusrite Scarlett 2i2 to make sure.
I was starting to think I was just having ear fatigue, but it's been a week and I was away from it for 3 days. If the clip sounds normal to you then maybe it is my ears.
So I'm willing to listen to any advise on how to proceed. Anything else I should try? Should I call Kemper?
