Mine is stack knob configuration, I generally have the following balance:
Everything Maxed - 50% of my playing (organic and natural sounding to my ears, nice brightness)
Neck full with tone maxed, Bridge full with tone off - 30% (warm with just the right amount of definition)
Neck Pickup solo'ed - 10% (almost Precision-like)
Bridge pickup solo'ed - 10% (great for Paul Simon stuff and simulated fretless)
