I have spent a lot of time trying to make profiles with some level of distortion and have had little success. Whether from a pedal in front of the amp or from the amp itself, every profile has a "dull" top end or just doesn't behave like the original. Refining helps some but it changes the character of the profile in other ways and, to my understanding, was considered unnecessary since a firmware update in 2015 or so. Attached are two audio clips to demonstrate my experience. Each has a lightly distorting Deluxe Reverb playing a looped phrase while I toggle between the reference and Kemper amps (in that order) after profiling. Can provide more clips if necessary. Please chime in with your two cents. Thanks
