Nope. The coils are de-tuned a bit (fewer turns) and wired in series.
2. If so, is it possible to wire in a toggle that, like the one in the L series, that will switch them from parallel to series?
3. Or...is it possible to wire in two toggles--one for each pickup--that will individually switch them from parallel to series?
4. Or...is it possible to wire in two 3-position toggles--one for each pickup--that will individually switch them from parallel to single coil to series, like the one in the Kiloton?
It's possible if you're very careful. Desolder the existing shorted leads, extend them and bring out to the cavity individually. Care must be taken to not break coil wires.
When Paul was doing the dev work on the pickups and preamp, he found that the bass just sounded better in series and he could control preamp clipping by just keeping the pickups output in check. In the M Series they were trying to eliminate the toggles in favor of the controls; basically taking an L-2000 that some viewed as overly complicated and modernizing it a bit with the fully active preamp. So if you were to split out the coils, you'd probably find a notable reduction in oomph when in parallel mode.
The M Series electronics are kind of a package deal, all designed to work optimally as designed. This is different than the L Series where we'd put a third party preamp in and keep it turned down a bit just to not clip anything.
