Depends on the genre for me,
Reggae, bridge perhaps 10% N 100% & T 0%...I use some tone for definition every now and then.
Dub as above but bridge 0%
Modern funk, all 100% but I adjust the tone for taste (all tastes like chicken to me )
Vintage soul N 100% B 50% T 50%...this is my most common setting.
Fusion/Jazz, I like N 0% B 100% T 50%-0%
These are just my preference. I'm sure fingers & feel, strings and amps account for a lot of the sound too. Also my favourite is to have the concentric pots set up and have tone on each pick up...loads of variations to be had.
