If I connect my Kemper power rack to a Bogner 2x12 OS guitar cab, I get a real good tone without changing the monitor EQ I can leave all knobs at the neutral position. But if I line the Kemper out to a PA system ( main outputs ) and I choose (the same) Bogner 2x12 by simulation, I have way to much Highs and Presence and not enough Mids and I have to tweek the main output EQ a lot to get the same tone ( or the EQ on the mixer of course ) Shouldnt this be the same as the real cab ? I understand that the Kemper sound fizzy if the Cab sim is accidently turned off , but even iff its on, there are still some cab-sim types that give to much Fizz and highs The fizz problem is gone if I choose another type cab ( like a marshall 4x12 greenback ) so its not a big problem but Am I doing something wrong ? ?( Greatings Dorrus
