Do you have a DAW running at the same time? I discovered having Logic running simultaneously screwed it up.
EQ wouldn't help here unless you're doing it at the application level and not with the sound card itself if that makes any sense.All depends on many factors even if you got any eq set in your pc sound card. For example intro to Sweet Child o Mine it will sound nearly spot on but when you play riffs it sounds thin... and im pretty sure thats the way Kemper Profiles which makes no option for further alterations.
I started using a low pass filter and that seems to help out a lot with getting rid of that sizzle. Is there a specific place the low pass should go in the chain and a frequency range I should focus in on? Im new to all this stuff. I also think that going AMP -> CAB -> TM sounds better than just AMP -> TM, im assuming, because I am going straight from the AXE to FRFR QSC K12's. Without a cab block every TM attempt is way too thin...unless I am doing something else wrong. I feel like I have definitely gotten closer than I was with tone matching but Im still not quite there yet.
