I own a Kemper stage for a month now and I am really happy with it! using it exclusively with my AKG K550 Headphones (32 Ohms).
In some of the low gain / early breakup profiles (but not all of them ), if I am strum a little bit harder the sound of the drive sound really digital/fuzzy through my headphones.. although the Kemper doesn't indicate there is a clipping problem.
I have to mention I didn't try the profile with another headphones or through studio monitors already.
Some of the profiles I tried :ToneJunkie JTM 45/100 , Mbritt Morgan JMI/JS..
Does anyone have an idea what could be causing this? The only thing I can think of is maybe the Impedance of the headphones
EDIT: could external sound card help? instead connect the headphones directly to the Kemper
Thanks in advance!
