So on my fender strat, which has Humbucker Singlecoil, Singlecoil, I decided to do something similar the one on alexplorer.net his "Black strat 2.0" version.
To sum up: He uses push/pull pots to do Series and Parrallel, he also has a phase switch for the middle pick up.
The differences: I have a HSS, also I had an ON/ON/ON switch with the humbucker. Also I used switches (DPDT ON/ON) instead of the two push/poll pots. Besides that, I wired it exactly as the page states.
My problem: The two series/parrallel *AND* phase switch turn off the sound completely depending on the what setting the 5 way selector at (specificily the bridge, bridge+mid, mid turn off during series switch, Mid, Mid+neck, Neck turn off with parrallel switch). What am I doing wrong? I tried removing both phase switches, still the series/parrallel switches turn off the sound completely in some of the settings. I also tried using my two tones as series/parrallel benders, *STILL* they would turn off the sound completely in some locations.
To add: i have 2 texas specials, the bridge is a pearly gates. The guitar goes completely quiet when I turn the phase switch(bridge) whenever it is in position 5 or 4 (bridge or bridge+mid). Also the guitar goes quiet in position 3,4,5 when i turn the parrallel blender all the way up.
I have modified the previous schematic and will send it if it would help.
