I'll add my .02
I am a long time p bass player w/flats.
I have 3 P Basses with different configurations of electronics and pickups.
Before you do anything major, put some sort of good flatwound strings on, you will not believe the difference in tone.
I have Chromes, Fenders, and Sadowskys, all have that old school thump and are not "zingy' bright like a new set of round wounds are.
Chromes are a bit brighter at first, but mellow out into a nice round tone.
The new fender flats are actually made by D'Addarrio and have a similar sound to chromes (hmmm....).
Sads are made by La Bella to Roger's specs and are a great tone, very big and full.
Do flats first and see what you think before modding the electronics.
BTW, I had one of those S1 P Basses and the switch does not color the sound in series.
Cheers!!
