This thread will attempt to include a modicum of common (and not so common) ways of splitting and tapping pickups. It is meant for one pickup (intra-pickup) and not meant for wiring schemes that encompass more than one pickup (inter-pickup). First, a "corrosion free" template (if you "know" jpegs, you know). i37.photobucket.com/albums/e84/cekikta/Wiring/Modules/Split_Blend_Template_20071025.pngThis is for a single coil/both coils in series/other single coil selection with a three position DPDT Center-ON/SP3T/DPDT ON-ON-ON switch. This is for a parallel coils/top single coil /coils in series selection with a three position DPDT Center-ON/SP3T/DPDT ON-ON-ON switch. Note that there are no hanging coils (unless the structure itself is elevated).

Chris - this could be a useful thread. How about a version of the first diagram, which avoids the hanging coil? I think it could be done with an on-on-on , and an order of series, top, bottom. Plus, I reckon the Red-Rhodes 'tap using the tone pot' is another good one.
cheers

John,
I'd thought about changing the selection ordering but wanted to keep it symmetrical (this was for two single coils, a Tele and a Strat bridge) that was wanted for VG3000.
Reordering the selections does allow no hanging coils, if shorted coils are allowed, this can be done with a SP3T Center-OFF. If only one shorted coil is allowed, the above single/series/single can be done symmetrically.
Some dislike hanging coils, some dislike shorted coils. My experiments by plucking a note and then rapidly shorting and unshorting a non-contributing coil seemed to be much easier to hear than a hanging coil switched on and off of the signal node.
In theory, a hanging coil will act as a high-frequency coupled coil into the signal node. In essence, it forms a series LCR network coupled thru the parasitic and shield capacitance to signal common. This capacitance is quite small, on the order of picoFarads and should only couple in the very highest frequencies. On a humbucker, while this won't make the pickup hum canceling at 50/60 Hz, it WILL help for high frequency interference.
But, YMMV
