I just read your post. I am sort of dense with computers but I have a schematic that would probaly work for you. If you could tell me how to attach a file or upload a picture to the PG website, I will get this out for people to look at. The guys at Seymour Duncan verified this for me. It basically is a switch combo that does the following:
Has an on/off for each pickup
Has a series/split/parallel for each pickup
Has a phase shift for each pickup
Has a Volume and Tone for each pickup
What I did was use:
a Push/Pull DPDT for the volume and on/off
a Push/Pull DPDT for the Tone and the phase
an On/On/On switch for the series/split/parallel
I use three Humbuckers with this on my guitar. I stopped counting at around 80 different combinations. It is not to difficult to solder and looks pretty cool (assuming you use small nobs and switches to keep the 6 nobs and three switches from spreading out all over the face of the guitar).
Just tell me how I can upload this or where I should send the schematic and I will send it off).
