Yeah I can see how you would feel that.
I don't vibe off the Direct stuff...I originally started with direct profiles playing through a real cab because I thought I wanted to retain some of the "realness?"
But with in a week I started to feel like everything sounded the same, like hearing a Super Lead to a Bogner Ubershall - had very little sounding differences/character.
Obviously thats because its all going through the same cabinet for coloring the tone. But I decided to go to a Full Range Cab by Laney and now I can get the intended vibe from everything. The differences you feel and hear from profile to profile are much more satisfying that way.
Granted im a new kemper guy for about the last 4 months...but I feel like I couldn't pick out what amp I was playing by attempting to detect the nuances from a Di Profile like I can when its a full profile with certain cabs and mics on it.
Might be the boat your in?
