Bass Pickup Positions, and Combinations - Bass With 5 Pickups 

Here's a demo of a bass I modded with 5 pickups, to test how different pickup positions and combinations (series / parallel) affect tone.
In each of the sound demos, I play the same 21 example pickup combinations, in the same order.
Timestamps:
Fingerstyle, roundwound: 1:43
Slap, roundwound: 3:20
Pick, roundwound: 5:09
Fingerstyle, flatwound: 7:46
Discussion / conclusions: 9:38
String isolation test: 11:57
Sympathetic resonance: 12:29
Special thanks to my daughter's LOL Dolls, who photobombed half the shots. :)
More info:
Pickups are all Dimarzio Area Js side-by-side humbuckers, with separate wiring to the "E-A" and "D-G" coils. The 3 pickups on the bridge side are the bridge-spaced version, and the remaining 2 are the neck-spaced version, to best follow the string spacing.
In all demos, volume and tone are completely open (100%). If more than one pickup is on, they're equally mixed.
Controls and electronics are the same as a Jazz (or Precision) bass, all passive.
The extra switch between the knobs is a tone capacitor selector switch, but for all of the demos it's set to the same value as a stock Jazz (or Precision) bass.
Bass is direct into a Focusrite Scarlett interface. Only "effect" is some light compression.
Strings on roundwound demos: DR FAT-BEAM (FB-40)
Strings on flatwound demos: Thomastik-Infeld Jazz Flats (TI JF344)
If you're interested in the demo basslines, they're based on:
Intro: Original (my band's track).
Fingerstyle, roundwound: One Nation Under A Groove (Funkadelic), live 1981-04-17 Landover, MD show. Bassist: Rodney "Skeet" Curtis.
Slap, roundwound: Motor-Booty Affair (Parliament). Bassist: Rodney "Skeet" Curtis.
Pick, roundwound: Original (my band's track).
Fingerstyle, flatwound: Help Is On The Way (The Whatnauts). Bassist: Rodney "Skeet" Curtis.
You guessed it, I'm a huge Skeet fan. Thank you Skeet for some of the best basslines ever recorded!
