All the clips are recorded in one session, and to minimize the number of variables between clips, I use these settings on all clips: Bass = 5, Treble = 5, Reverb = 3, Speed = 7, Intensity = 3, Bias Tremolo is selected, No Boost (bright) is selected, No Cut is selected, and the rear panel NFB switch is set to Normal. The Master Volume is set around 2.5, but reduced slightly (~2) for the clips with ChA volume at 10 (the latter 3 clips) to keep the room and mic levels roughly constant.
