Not quite. The pickups are split coil but the neck and bridge coils are each connected in series while the middle pickup coils are connected in parallel. You can tell by looking at how each pickup is wired to the selector switch. The picture below is old but shows the connection types.
- If red and green wires from the same pickup join at one contact while white and black wires from that same pickup join at a different contact, then the coils from that pickup are in parallel.
- If the red wire from a pickup connects to one contact, the white wire from that pickup connects to a different contact, and green and black wires are pulled back together connected and taped, then the coils from that pickup are in series.

- The pickup selector switch can then align the individual pickups in any of the predesigned configurations.
1. Series bridge pickup is soloed
2. Series bridge pickup is aligned in series with the parallel middle pickup (Stingray like)
3. Series bridge pickup is aligned in parallel with the series neck pickup (jazz bass)
4. Series neck pickup is soloed.
Series has a fatter and stronger tone than parallel. Soloing one of these pickups with coils wired parallel sounds weaker and thin by comparison.
The way these pickups are designed, too much of any one thing sounds unbalanced. Two pickups aligned in parallel with their internal coils also parallel will have lots of highs and scooped in the mids with a detailed but weak signal that needs a lot of boosting. At the other extreme, two pickups aligned in series with their internal coils also in series will have a lot of low mids and loss of highs with a strong signal that needs to be turned down to match volume. Dingwall has tried all these combinations (as have I through my own experimentation) and settled on these combinations as optimum and widely accepted. 6-way aftermarket switches and individual pickup S/P switches can be used to offer more combinations but IME, after playing with many combinations there will probably be 3 or 4 favorites that get all the use.
