This wiring scheme utilizes two Fender S1 switches to accomplish 2 different sets of pickup combinations for the 5 way pickup selector switch, one set similar to SSS mode of a Strat and one featuting full humbuckers plus two different coilsplit pairings of those humbuckers. Positions 2 and 4 of either mode feature hum-canceling coilsplit pairs. The Master Tone S1 switch/pot is used to switch btw SSS mode or HH mode. Following are the pickup combinations for each mode: Master Tone S1 not pressed (up) = HH mode 1. Bridge HB 2. Bridge / Neck INNER coilsplits 3. Bridge / Neck HBs 4. Bridge / Neck OUTER coilsplits 5. Neck HB Master Tone S1 pressed (down) = SSS mode 1. Bridge Inner coil 2. Bridge Inner coil/ Middle pup coilsplit 3. Bridge Inner coil / Neck Outer coil 4. Neck Outer coil / Middle pup coilsplit 5. Neck Outer coil The Master Volume S1 is used to get Middle Pickup alone (traditional Strat Position 3). Master Volume S1 not pressed (up) = Master Tone S1 settings prevail Master Volume S1 pressed (down) = 5 way superswitch and Master Tone S1 settings are bypassed. Middle Pickup alone is active, *not* coilsplit so it IS hum-canceling. imgur.com/gallery/P2lLeCkThis wiring scheme is sensitive to the magnetic polarity of the singlecoil pickup in the middle position. The magnetic polarity of the Middle pickup dictates which coils of each humbucker are targeted to be active during SSS mode, to ensure hum-canceling coilsplit pairs. This paticular arrangement is based around a Seymour Duncan (SD) Stack type singlecoil designed for Middle Position. These types of pups have a Main coil with a South magnetic polarity. Whereas Bridge and Neck position versions of the SD Stack type pickup have a Main coil with a North magnetic polarity. So in this case, this wiring design has targeted the humbuckers' North coils to be active during SSS mode. Also, in order to have hum-canceling in the Both Inners and Both Outers coilsplit pairings of Positions 2 and 4 in HH mode, one of the humbuckers needs to be minimally Reverse Polarity (magnetic) from the other. This need combined with considerarion of popular opinion that the outer coil of a Neck humbucker is more desirable as a standalone splitcoil than the inner coil of the Neck humbucker for emulation of Strat Position 5 type tones, drove the decision to make it the Neck pickup and not the Bridge pickup to have its magnet flipped to achieve Reverse Polarity for this scheme.

FYI: I updated the diagram (and Imgur link) in the original post so that the 470K resistor used with the Middle Pickup is only in the circuit when the Middle Pickup is active by itself (traditional Strat Position 3). This should help prevent that resistor having a darkening effect when the Middle Pickup is paired with the Neck and Bridge pickups in SSS mode Positions 2 and 4.

Congrats on working all that out (haven't checked it though!)
I'm sure it sounds awesome!

I'm going to have a look at it, i love new designs... some thing different than the NORM because I'm so Ab Normal try and redraw it first, never a fan of snakes and ladders (always love your use of colours tho, makes it easier to find things) Some bits catch my eye and im not sure why yet.

@angellahash, sorry, but the legend table results you came up with are not accurate. For example, it mentions that in certain S1 positions that the Middle pickup is split so that the North coil is active (and the 470K resistor active in the circuit). That never occurs. The middle pickup is either wired in series at times (w the 470 resistor active in the circuit), or split so the South coil is active (and the resistor not in circuit). The legend at the bottom of my diagram states this.
Also, you use symbols + and x in your legend table. What do you mean by them? Standard practice is to use / for parallel connection and + for series connection. In my diagram, all of the pickup combinations in positions 2, 3 and 4 are parallel /.

Personally the X and + seem to be used in this Guitar are . is normally used as AND in Digital Electronics + is used for OR I dont like the wording Series and Parral depends on how you look at things from point of view Standard Index for Resisters but not Capacitors!! Lets Try again .. not sure why cant draw the circuit out but hay Try and show the workings out as i should do in MATHS I DIDNT Read what you said on the Diagram i COPIED the Diagram on to a Circuit Diagram and then FOLLOWED from there. My HOME City Football Club SINGS "Greatest Football team in the WORLD" they on the BRINK of being SEMI-Pro they are that BAD, just because they say they are GREAT doesnt mean its REAL!!! So all the MIDDLE goes via the MV, so i must of made a ERROR when coping it out!! Circuit on this site using "x" and "+" for how Pickups are linked (I didnt just make it up)-------------- Master Tone S1 not pressed (up) = HH mode 1. Bridge HB 2. Bridge / Neck INNER coilsplits3. Bridge / Neck HBs 4. Bridge / Neck OUTER coilsplits5. Neck HB all the rest about the same as you said, (i dont care what way Middle Pickup is in relation with the Bridge & Neck Pickups)
