I notice that my idea for a bass cut using a cap in what I once called a broadbucker configuration is now widely used in many settings.
Your diagram is impressive and I like the idea that it preserves the original configuration.
However it lacks one combination that I find the most useful of all: the B+N out of phase which is quite essential to achieve a Telecaster sound.
With the right strings it is extremely charmful and I always use it for Pretenders or Reggae.
My own take on the Strat has it, but it lacks other goals that you have achieved.
Here is the diagram:
I apologize for the poor quality, but this was the first diagram I ever did.
The guitar is a Fender Stratocaster deluxe with a stock switch button that adds the bridge pickup in parallel.
So the first seven sounds are stock. I added an additional button switch that puts the neck pickup out of phase. I could have chosen the middle pickup, but that wouldn't give the B-N sound.
Moreover it has another curios sound, B+M-N, which sounds like the transistor radio in Wish You Were Here, good for crappy solos and funky rhythm guitar. I guess you get similar sounds from your out-of-phase-combinations.
This brings the available sounds on my guitar to ten.
Then I noticed that the other side of the stock switch was still available and so I used it to throw in the bridge pickup in series.
This is the reason why I don't preserve the original config, since with all buttons pulled the selector switch in bridge position gives a humbucker of BxM.
For switch positions B and B+M the original config is preserved with the add-button down, for positions M, M+N, N with add-button up.
In the humbucker configuration the middle tone control can be used to mix certain frequencies between the two pickups which results in a broadened sound with full bass from the humbucker and stingy trebles only from the bridge pickup.
This is what I gain and it brings the available sounds to twelve.
This is the guitar. The lower button was from stock, the upper one was added by me.
