Nothing at all wrong with the existing setup. Currently with 2 Millis, 3 Cirrusses, and a GV.I am always amazed at folks that change the electronics in Millennium or Cirrus basses. The OEM electronics are one of the reasons these basses are so good. I would wait for one to pop us that is all original.
The only mod done to any of them is the Milli pre I swapped into the Maple Cirrus. I like to add in some low mid, given the option. Not in a rush to change the Walnut or Bubinga topped ones.
