I actually just bought the 90w Mark V like a week ago (very good deal from a friend).
Haven't had a chance to really use it much, but I kind of based settings off of Ola's video and it sounds pretty 'plug n play' through a mesa standard cab.
I am amazed at how much you have to knock out the 750 on the graphic to kill muddy mids. I probably would have never of taken that much out if I were tweaking it blindly from the start, haha.
