Is it possible to run 2x spin-a-splits through one potentiometer?

[Grindspine]

I am considering rewiring one of my older guitars with two spin-a-splits. I have one unused tone pot on that guitar, but would like to split both bridge and neck humbuckers. This is the closest Duncan wiring schematic I have found. I am assuming that the spin-a-split pot would be wired in place of the push-pull switch on the back of the pot in this schematic. I am wondering if signal would bleed from the unselected pickup's second coil though.

If the pot in the spin-a-split can be treated like the switch in the top schematic, then a spin-a-split should work if the red/white connections from each of the two humbuckers is connected. Am I reading that correctly?

No.

If the connections to ground via the red/white conductors meet, the coils of the two pickups are partially joined, regardless of how the pickup selector switch is positioned.

You would require a dual ganged pot.

Thanks, funkfingers. That makes a lot more sense.

A dual ganged potentiometer sounds like it'd be the perfect solution for that guitar.

Revisiting this topic:

If a typical mini switch were used for coil splitting, if a potentiometer was placed between the switch and the ground, would it be possible to control the amount of signal bleeding to ground through that one potentiometer?

I am having a local luthier rewire my guitar, but he was having trouble acquiring a dual-ganged potentiometer.

Yes. Kinda. You run into the same issue Funkfingers was talking about when in the middle position with the split engaged but the split pot on full - you have both slug coils in parallel, in series with the screw coils in parallel. It's actually a cool sound.

On a side note, has your luthier heard of the internet?
