I'm finding it never gets there. It only sounds good/close for the last ten or so seconds of refining, which is similar to the basic Match EQ in Logic. If I play chords then it'll sound very close if I then play those chords afterwards, but lead sounds lack definition and it lacks the feel/ability to clean up in a similar way to the real amp, if I play quietly then lower volumes sound right and it becomes more touch sensitive, much closer to the real thing, but at full gain the sound is dead, if I play lead lines then it sounds right for those lead notes, but chords lack bass. If I attempt all three or a mix of two then it doesn't work, only the last played stuff sounds close. I guess given Christophs response then all I can do is hope profile refining will continue to be improved and "refined" over time itself.
