The 6 way toggle is abysmal. Very flimsy.the new 6 way blade is perfectly fine.
I have a 6pos 4pole rotary in a guitar with an humbucker and a P-90, and it works really well. You have to get used to putting the switch in the correct position but its not too difficult. The pickups I have tap one coil of the humbucker so its not truly split just a lower output on one coil to make it sound thicker than a normal split humbucker. The winder is a forum bro and he calls it splat.

The way I have it set up is the bridge splat or split for other pickups and the p-90 is tapped to vintage output. While in series its actually hotter than the full humbucker so its great for a boost and for solos. I personally wouldn't do it with 2 humbucker just because of the volume jump. But 2 pickups in series is a really cool sound. It gives you the fatness of the neck with the bite of the bridge and pushes the amp a bit harder.That's cool - I have had Guitars with a lot of wiring options etc.-
I have even tried stacks with a switch to throw the two coils of the stack in parallel with each other- very transparent and super 'quacky' in almost any combination...even with a Humbucker= fat quack ('Mainiac ' by Michael Sembello for example ).
But the one thing I have never tried is humbuckers in series with each other for a phatt Jazzy Sound - does it work well for that ?
I like the idea of a 6 way
The 6 way blade is simply made by oak, like the usual 5 ways. These are fine. Allparts sells them.
