Profiling with 3.0, I am lost

  • Hi guys,


    I installed firmware 3.0. I have a diezel vh4 and a koch dummy load/attenuator with di output. So I hooked up the diezel speaker output to the dummy load of the koch. Then direct out -10db (0 db is to loud) into the return input (jack) of the kemper.


    Front input of the Kemper>guitar and kemper direct out/send to the input of the diezel.
    In profiling mode I hear my amp (tested the koch direct out to my focusrite daw and have heard that typical di sound).


    Problems:
    -I can only use a very low volume on the diezel or it starts to feedback/make a feedback kinda sound
    -the profile doesn't come close to the original


    I quess I am doing stuff wrong, but what?


    There is no cab attached. With the koch it is not necessary.


    Goal is to get a back up from the diezel for home and live purpose (Diezel itself for practise) through a real guitar cabinet.
