Howdy... I'm right in the middle of profiling my Mesa Formula Preamp and I'm running into an issue trying to get a clean direct sound.
I have the guitar plugged into the kemper front panel input, and the Formula's direct out (non cabinet sim output) going back into the Kemper's return input. When I attempt to make a clean profile with cabinets turned off, the resulting profile always seems to have the high frequencies rolled off, like the kemper is forcing a cabinet on. When I compare the reference amp to the kemper profile, the reference amp has the bright direct sound as if the preamp was plugged directly into my console but the kemper profiles sounds as if the high freq's are being rolled off. Doesn't sound anything like the reference amp.
Any suggestions? Does this have something to do with the initial kemper profile I have selected when I start the profiling process?. I just can't seem to get that same bright direct sound I get from the reference amp. Maybe the KPA can't do a direct non-cab preamp direct sound?
