Adding a push/pull for a Bartolini humbucker?

[Stagelab]

Just got a fretless with a Bart humbucker and a single coil but the humbucker is closest to the neck. It’s passive and there isn’t a switch. Pretty sure the humbucker is wired in parallel but not positive. I don’t know the model of the Barts.

What would I need to do if I wanted to install a push/pull vol pot for switching between parallel and series? Is there a three position push/pull out there for parallel, series and single coil? I’d rather not drill any holes for a switch.

Any recommendations for a push/pull pot and wiring instructions?

This is for guitar, but the wiring should be pretty much the same on bass: 1 Humbucker/1 Volume/Series-Parallel

Here is the Bart wiring setup. You can do a stacked volume/volume with a push pull on another pot to get the series/parallel/single and that gives you the single on either coil. That is how I have my passive stingray wired.

Having trouble accessing the PDF. I’ll try on my Mac later. How does the push pull work to give you all 4 options (series, parallel, single coil A, single coil B)? Do you mean using a 4-way rotary switch?

As a simpler alternative, could I just have a push/pull neck vol pot that switches between parallel and series?

Could I instead just have a push/pull neck vol pot that switches between parallel and series? Not as versatile but a little cheaper.

A single push/pull parallel/series is definitley do-able. Push/pull would gives 2 options. You could change 2 pots to push/pull to give you more options.

*edit. Guess @Bodeeni already covered this. I need more sleep.

If you have a volume on each coil it is like having two single coil pickups with full up being parallel humbucker.
