Ibanez True-duo Bucker?

[GodBlessTexas]

Does anyone know what the deal is with this setup? What are they doing differently to the humbucker to get a single coil sound that other people haven't done? They're literature says it's a patent pending technology, but they don't show more than that or go into details. Does anyone know the scoop?

Edited to add: I found the wiring diagram for the SA260, which has this feature. To me, it looks like other diagrams I've seen involving three wire humbuckers. I'm not exactly sure if it's patent worthy.

Basically, there are 2 non-normal things. They replaced the steel slugs in one coil with alnico magnets, as used in single coil pickups. This gives a different magnetic pattern than a magnet/slug combination. Also, they added a dummy coil to that coil so that when the pup is split it is like a stacked humbucker - a single coil sound, but noise-free.

There's a thread on Duncan's forum here:

Awesome, thanks for the information. However, looking at the diagram for the SA260, why would they make the single coil a stacked coil when it's only used in position 4 as a single, which also activates the middle pickup? I thought the point of the stacked coil was for noise cancelling, but if that's the case then why run it with the middle coil?

I think yours is an older diagram. The pup selections shown on the page I linked:

There's a push-pull pot on that version, so in position 5 you get just the single coil. I'd hope that the dummy coil is out of circuit in position 4, which as you say is naturally humbucking.
