My $0.02. Ignore the eq. Just mess with the sensitivity knob. That is where the magic mostly resides. I find the eq to be subtle seasoning, while the sensitivity is more towards the emotional mood swing control.
+1. I've been using Monique for less than a week and this has been my experience. I would add a second major tonal factor as the amount of drive that is weighted to Monique vs. the power amp. In the case of a de-Monique, I believe this relationship is fixed. My preference has been to drive Monique's line out at about the 3-4 o'clock position to maximize the effect of the preamp, and bring the external power section up gradually as needed.
