For me, figuring out how to work the Series I controls was the last piece of the puzzle.
It's a mixing board. Up until that point, I always favored having a Volume/Pan/Filter setup, (and still prefer it for most live situations) but having separate Volumes and Filters is a huge advantage. You can dial in or out just enough of whatever you want on either pickup/channel. That said, it's just another level of surgical precision for shaping your sound, but you can get in that target zone either way. It's just faster and easier with the simpler circuits.
Ironically, my older Distillate was modified to have a Pan function in place of its original pickup selector switch, and works just fine.
