Wiring single conductor humbuckers with push/pull mods - help please!

[fingerace]

I'm trying to figure out how to wire two mini humbuckers (which are single hot/ground conductor) with a master volume and master tone. With push pull mods for series/parallel (of one pickup to the other in the middle position) and for phase switching (of one pickup to the other, in the middle position).

I'm finding this diagram, but I'm not sure how it would apply to single conductor pickups:

I think what I'm trying to do should be possible with single conductor wiring... Any help would be appreciated!

Thanks

Are these Les Paul-type mini-humbuckers, or Firebird mini-humbuckers?

To flip the phase, you have to rework the wiring of the pickup to separate the baseplate ground and keep it grounded when phase is flipped.

As you can see in the diagram (since the red + white are not involved in the p/p switching) those are essentially 3 wire pups: black = lead, green = ground, grey = shield or baseplate ground.

Like Beau said, you need to keep the baseplate ground, the shield wire (the grey wire in the diagram) always grounded and separate from the ground wire (green in the diagram, but possibly different colors in your pups depending on the mfr. of your pups).

This is a common and popular mod

There is a version where you get a kill switch as a bonus

As stated important ground wire be kept seperate from circuit ground

I could post the schematics but others might be clearer than my scribbles.

Thank you for your replies.

The guitar is Gretsch baritone with stock pickups. Just two leads for each pickup... so I guess I cannot separate the baseplate ground from the coils without modding the pickup.

I felt the guitar needed all the high end it can get, so I found some 1Mohm pots... and since I was going to do the work, I thought a couple of push/pulls would offer some more usable colours.

I might just stick to the new pots for now, see how much difference it makes...
